Age of Cataclysm: I can light up the technology tree

Mo Zeyang ignored Lu Yongchang's correction.

At this time, his hands and feet were trembling slightly with excitement!

The originally troublesome problem was solved at this moment!

Such an incredibly silky smooth feeling!

Mo Zeyang believes that there is no more addictive feeling in the world than this!

His hands trembled slightly, and he carefully placed the black rectangular object in his hands on the experimental table, fearing that it would be damaged by his rough movements.

Lu Yongchang, who was on the side, couldn't help laughing after seeing Mo Zeyang's action.

"Calm down."

"At present, this thing is only a semi-finished product, and it still needs a series of purification work before it can be used as a raw material for photonic computer wafers."

"Besides, I haven't finished the introduction yet."

Mo Zeyang was stunned: "Any more?"

"certainly."

Lu Yongchang glanced at Mo Zeyang in surprise: "If it only has this simple property, how can it be the core material of photonic computers?"

As he spoke, Lu Yongchang stretched out his hand and dragged the holographic image beside him to his side.

"It's still similar to the properties of semiconductors."

"Based on information from Proxima Centauri."

"This kind of semi-transparent material does not have strong light transmission performance when the purity is high."

"but!"

"If we can add a little impurity to it, its light transmission performance will be greatly improved!"

"And different types of impurities will have different effects."

When Mo Zeyang heard this, his mouth opened slightly and his eyes were full of disbelief!

“Isn’t this the doping ability of semiconductors?!”

Mo Zeyang's tone suddenly became excited: "Well, is there any experimental data?"

Lu Yongchang nodded and slid his hand in the air.

In the holographic projection, several crude experimental records appeared.

"..." Mo Zeyang looked at Lu Yongchang with questions, "That's it?"

Facing Mo Zeyang's question, Lu Yongchang spread his hands, shrugged and said, "That's it."

"Don't ask me, I don't know what these big cockroaches are thinking in their heads."

"They actually delayed such an important experiment until 50 years later."

Mo Zeyang put his hand on his forehead: "Oh my God..."

“What a waste of natural resources!!”

He honestly believed that if this material fell into his hands.

He shows disrespect for science by sleeping 8 hours a day!

Lu Yongchang shook his head with a strange expression: "You can't say that."

"If they really get hold of this material, we probably won't end up well."

Hearing this, Mo Zeyang looked a little weird.

"Speaking of it, it seems to make sense..."

Lu Yongchang brought back the topic of deviation: "Although the experimental data is insufficient, based on the use of semiconductors, we can basically determine the direction of the next experiment."

Mo Zeyang nodded in agreement.

Compared with rectification, dopingability is of greater significance to photonic computers!

For example, semiconductors.

The reason why semiconductors can be made into triode transistors is inseparable from this property!

Pure semiconductors have very weak electrical conductivity, but semiconductors doped with impurities can greatly improve their electrical conductivity!

It can be divided into two types by the type of doping substance.

Silicon crystal doped with a small amount of phosphorus or antimony is an N-type semiconductor.

Silicon crystal doped with a small amount of boron or indium is a P-type semiconductor.

When the two are connected, they can become a PN junction.

The so-called diode is realized by a PN junction.

As for the triode, it is realized by a PNP junction formed by two PN junctions.

Through these diodes and triodes, various forms of logical operations become a reality!

To put it simply, the semi-transparent material in front of you is actually equivalent to the silicon wafer of an electronic computer!

Thinking of this, Mo Zeyang felt extremely excited!

He urged again and again: "Professor, quickly, verify the accuracy of the Proxima Centauri data!"

"I have a hunch that photon computers are already waving to us!"

"Don't worry." Lu Yongchang smiled faintly, "If a worker wants to do his job well, he must first sharpen his tools."

"If nothing else, the newly manufactured ion implanter should be arriving soon."

…

at the same time.

A Xuannv 2 slowly landed on the tarmac outside the laboratory.

The hatch opens slowly.

More than a dozen robots moved a machine out of the Xuannv 2 cabin.

"Professor, your customized ion implanter has arrived."

In the laboratory, Zero's voice suddenly sounded: "Do I need to move it in?"

Lu Yongchang was overjoyed: "Hurry, hurry, hurry!"

"Bring it in!"

"Put it in a prepared clean room."

"Copy that, Professor."

After saying that, Zero's holographic image slowly faded.

"Ion implanter?" Mo Zeyang looked at Lu Yongchang with a strange expression.

"Are you using it as a silicon wafer?"

Lu Yongchang said with a smile: "It's almost the same, but I made some changes to make it more suitable for processing semi-transparent materials."

As he spoke, he opened his legs and walked towards the clean room set up next to the laboratory.

…

In a clean room.

A machine similar to a silicon wafer ion implanter is quietly placed in the center of the clean room.

Lu Yongchang and Mo Zeyang wore dust-free clothes and slowly walked into the clean room.

Looking at the machine in front of him, Mo Zeyang took a deep breath.

"Professor?"

"Are we going to start the experiment now?"

Lv Yongchang nodded without comment: "Of course."

"We are not Proxima Centauri. The sooner we master this key technology, the better!"

As he spoke, he carefully took out a piece of semi-transparent material cut into thin slices.

Even though it was a thin slice, it still appeared black and light gray to the outside world.

The reason is simple. The semi-transparent body with higher purity does not have high light transmittance.

In the absence of direct strong light, even the side that allows light to pass through looks gray.

Lv Yongchang quickly put the semi-transparent material into the ion implanter.

"Zero, start the ion implanter."

A slight humming sound followed.

In a very short time, the ion implanter was evacuated into a vacuum.

Then, the accelerator started.

Specific ions were accelerated by the electric field and blasted straight towards the thin semi-transparent body!

Under Zero's precise control, these ions penetrated into the material gaps of the semi-permeable body at just the right speed, and then perfectly combined with it!

Time passed by minute by minute.

The buzzing sound gradually became weaker.

"Professor, the ion injection has been completed."

Zero's reminder sounded.

Lv Yongchang held his breath slightly, stepped forward and opened the hatch of the ion injector.

A piece of black flake-like material lay quietly in front of him.

He carefully picked it up and turned it over.

Suddenly it became clear!

It was like a transparent glass!

At this moment, the semi-permeable body injected with a large amount of impurities completely revealed its true appearance!
