February 19.

Huang Xiuyuan and his group finally returned to Shanmei.

As soon as they returned to Shanmei, Lu Xuedong came to him and the two came to the semiconductor laboratory.

After changing the full-body protective clothing, the two entered a clean room. On a workbench, Lu Xuedong excitedly pointed at a translucent film: "Xiuyuan, look at this."

The film is very thin and there is a kind of clip on the four sides that firmly hold the film.

"The film woven by nanowires?" Huang Xiuyuan obviously knew what it was.

Lu Xuedong nodded: "It's nanowires. Three days ago, we successfully synthesized silicon nanowires with relatively strong strength, and the strength can be maintained for braiding operations."

Open the internal computer next to it and find the detection report, which also has the detection screen of the lens electron microscope.

He saw the neatly arranged pictures of silicon atoms, which was almost exactly the same as the pictures in his memory.

Huang Xiuyuan turned the chair: "Where is phosphorus, boron, arsenic, aluminum?"

"There are some ideas for phosphorus wires and arsenic wires. Hexagonal silicon oxide can synthesize phosphorus nanowires, but the current strength is still problematic and is being improved."

Lu Xuedong paused for a moment and continued: "In terms of boron and aluminum, I tried it from pentaneous silicon oxide. Although I barely passed, I couldn't synthesize nanowires."

Huang Xiuyuan knew this situation clearly, and he expressed his ideas:

"No need to waste time on boundless silicon oxide, why not start with the heptamorphous silicon oxide."

"Shened-sided silicon oxide? But the oxygen group does not have suitable semiconductor materials." Lu Xuedong was a little puzzled.

"Haha." Huang Xiuyuan smiled: "Why don't you let Oxygen be the leader?"

Lu Xuedong was stunned and instantly reacted: "This is indeed possible. It's just how to remove the oxygen atoms mixed in it after the nanowires are formed?"

"You won't forget, another characteristic of nitrogen 16, right?"

After being reminded by him, Lu Xuedong's eyes suddenly lit up.

Because in addition to its strong catalytic function, nitrogen 16 has another function. Under strong ultraviolet rays and specific temperatures, nitrogen 16 molecules will decompose into nitrogen. If there are oxygen atoms around it, nitrogen 16 will forcibly combine with oxygen atoms to form nitric oxide (NO).

Even the oxygen atoms in the oxide cannot prevent the forced binding of nitrogen 16.

In this way, nanowires formed by alumina and boron oxide can be removed through nitrogen 16 to form single aluminum nanowires and boron nanowires.

Lu Xuedong planned to try it, but Huang Xiuyuan knew the synthesis technology: "Leave this part to me!"

"good."

Huang Xiuyuan, who returned to scientific research, tried to form nanowires with more than a dozen researchers.

In the Materials Laboratory.

A seven-sided silicon oxide-sieve sieve, a funnel-shaped upper container filled with boron oxide powder.

These boron oxide (diboron trioxide) powders are all sieved single-molecule states and are also the most suitable states as synthetic raw materials.

Since boron oxide generally exists in an amorphous state, it is usually difficult to form crystals, but crystals can also be formed after high-intensity annealing.

After trying more than a dozen times, Huang Xiuyuan improved the experimental heating method and used a laser to focus on the ejection outlet of the heptamorphic silicon oxide.

This is a very meticulous job. After burning hundreds of seven-sided silicon oxide films in succession, a qualified position was debugged.

The laser focus position is only about 23 nanometers away from the outlet of the heptare silicon oxide, which is already the limit.

It’s not that you can’t keep approaching, but when you get closer to the nozzle, the laser will quickly burn the heptamorphic silicon oxide film.

Even at this distance, a seven-sided silicon oxide film can only work continuously for up to 10 to 12 hours, and will be completely scrapped.

After laser sintering, a boron oxide nanowire was indeed formed.

Huang Xiuyuan ordered: "Test the strength and other characteristics of the boron oxide nanowire immediately."

"clear."

The researchers were also very excited, and everyone was in a state of excitement.

Wu Can, a researcher in charge of the test, put the boron oxide nanowire into a tensile strength tester, and then carefully increased the tensile strength.

Several other researchers tested cross-sectional diameter, resistivity, melting point, thermal conductivity, magnetic properties, etc.

After the sieve and laser sintering, some of the physical properties of the boron oxide nanowires formed have changed.

For example, although the tensile strength is not as good as carbon nanotubes, it is almost in line with ordinary steel wires.

Wu Can from the laboratory took the test report and reported to Huang Xiuyuan: "Mr. Huang, the strength of the boron oxide nanowire is in line with expectations."

Huang Xiuyuan immediately started the next experiment and turned around and ordered: "Prepare the oxygen atom stripping experiment."

"yes."

The oxygen atom stripping experiment is to place boron oxide nanowires in nitrogen 16 powder. The entire container is made of silicon nanoplating because nitrogen 16 will bind to oxygen atoms, and the container must be silicon nanoplating.

The laid boron oxide nanowire is covered with a layer of nitrogen 16 powder, and the bottom of the container starts to heat. When the temperature reaches the designated position, strong ultraviolet irradiation is activated.

Under temperature and ultraviolet light, nitrogen 16 molecules decompose rapidly, and nitrogen 16 near boron oxide nanowires combine with oxygen atoms in boron oxide to form nitrogen monoxide.

When all the nitrogen 16 is decomposed, only boron nanowires are left in the container.

Several researchers took the boron nanowires gently, took them out of the container, and immediately sent them to the laboratory for testing.

Wu Can and others were responsible for the testing.

After the oxygen atoms are stripped away, the remaining boron nanowires become significantly weaker, and the tensile strength is similar to that of ordinary cotton thread.

Huang Xiuyuan is actually very clear about this result. Although this tensile strength is fragile, it is not impossible to solve it.

If the strength of a single-line boron nanowire is insufficient, it can be turned into a boron nanorope through multi-wire braiding.

Moreover, in related applications, there is actually no high requirement for the tensile strength of boron nanowires, and only needs to reach the strength of ordinary cotton ropes.

The research and development of boron nanowires was completed, and the subsequent aluminum nanowires and copper nanowires were also successively developed by Huang Xiuyuan.

On the contrary, the phosphorus nanowires and arsenic nanowires on Lu Xuedong were in trouble.

In the lab's lounge area.

Lu Xuedong took a sip of black coffee and then smiled bitterly: "Your side is too fast, why don't you try the phosphorus nanowires and arsenic nanowires?"

Upon hearing this, Huang Xiuyuan shook his head: "It's better to follow the established route. The production through laser sintering will consume too much silicon oxide film."

"That's true. It's really a lot of trouble to use a film for more than ten hours." Lu Xuedong also temporarily put down his idea of ​​changing the route.

If the pentaneous silicon oxide film can be used to directly generate phosphorus nanowires or arsenic nanowires of appropriate strength, they will have all the raw materials they need.

"I believe in you," Huang Xiuyuan patted his shoulder.

Lu Xuedong cheered up again, and Huang Xiuyuan brought people to join, and after more than a week.

Finally, a phosphorus nanowire, or phosphorus nanorope, was synthesized, because the strength of a single strand of phosphorus nanowires has not been increased, so they can only reduce the requirements. Five phosphorus nanowires are woven to form phosphorus nanoropes.
Chapter completed!
