Cataclysmic Era: I can unlock the tech tree

Mo Zeyang ignored Lü Yongchang's correction.

At this moment, he was so excited that his hands and feet trembled slightly!

What was originally a troublesome problem was easily solved at this moment!

This incredibly smooth and silky feeling!

Mo Zeyang believed that there was no feeling in the world more addictive than this!

His hands trembled slightly as he carefully placed the black cuboid on the lab table, afraid that his rough handling might have damaged it.

Lu Yongchang, who was standing to the side, couldn't help but chuckle when he saw Mo Zeyang's action.

"Calm down."

"Currently, this thing is only a semi-finished product and needs to undergo a series of purification processes before it can be used as a raw material for photonic computer chips."

"Besides, I haven't finished introducing myself yet."

Mo Zeyang was stunned for a moment: "There's more?"

"certainly."

Lü Yongchang glanced at Mo Zeyang in surprise: "If it's just this one simple property, how could it possibly be the core material of a photonic computer?"

As he spoke, Lü Yongchang reached out and dragged the holographic image to his side.

"It still has similar properties to semiconductors."

"According to the data from the Proxima Centauri."

"This semi-transparent material does not have strong light transmission properties when it is of high purity."

"but!"

"If even a tiny bit of impurity could be added, its light transmittance would be greatly improved!"

"And the effects will vary depending on the type of impurities."

Upon hearing this, Mo Zeyang's mouth opened slightly, his eyes filled with disbelief!

"Isn't this the doping property of semiconductors?!"

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

Lü Yongchang nodded and then swung his hand in the air.

Several rudimentary experimental records appeared in the holographic projection.

"..." Mo Zeyang looked at Lü Yongchang with a face full of question marks. "That's it?"

"Don't ask me, I have no idea what these giant cockroaches are thinking."

"They actually delayed such an important experiment for 50 years."

Mo Zeyang reached up and rubbed his forehead: "My God..."

"What a waste!!"

Honestly, if this material fell into his hands...

His ability to sleep for a full eight hours a day is a disrespect for science!

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

"If they really get their hands on this material, we probably won't have a good ending either."

Upon hearing this, Mo Zeyang's expression became somewhat strange.

"Come to think of it, that makes sense..."

Lu Yongchang steered the conversation back on track: "Although the experimental data is insufficient, based on how semiconductors are used, we can basically determine the direction of our next experiments."

Mo Zeyang nodded repeatedly in agreement.

Compared to rectifyability, doping capability is more significant for photonic computers!

For example, semiconductors.

The ability of semiconductors to be manufactured into triodes is inextricably linked to this property!

Pure semiconductors have very weak conductivity, but semiconductors doped with impurities can have significantly improved conductivity!

Based on the type of dopant, it can be divided into two types.

Silicon crystals doped with small amounts of phosphorus or antimony are N-type semiconductors.

Silicon crystals doped with small amounts of boron or indium are P-type semiconductors.

When the two are connected, they form a PN junction.

A diode is a device that is made using a PN junction.

As for triodes, they are achieved by forming a PNP junction from two PN junctions.

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

Simply put, the semi-transparent material in front of us is actually equivalent to the silicon wafer of an electronic computer!

Thinking of this, Mo Zeyang became extremely excited!

He urged repeatedly, "Professor, hurry, quickly verify the accuracy of the Proxima Centauri data!"

"I have a feeling that photonic computers are already beckoning to us!"

"Don't rush." ​​Lü Yongchang smiled faintly. "A skilled craftsman must first have the right tools."

"If all goes well, the newly manufactured ion implanter should arrive soon."

……

at the same time.

A Xuan Nu II slowly landed on the helipad outside the laboratory.

The hatch slowly opened.

More than ten robots carried a machine out of the cabin of Xuan Nu II.

"Professor, your custom-made ion implanter has arrived."

In the lab, Zero's voice suddenly rang out: "Should we move it in?"

Lü Yongchang was overjoyed: "Quickly, quickly, quickly!"

"Bring it in!"

"Place it in the prepared cleanroom."

"Understood, Professor."

After he finished speaking, Zero's holographic image slowly faded.

"An ion implanter?" Mo Zeyang looked at Lü Yongchang with a strange expression.

"Are you trying to manufacture it like a silicon wafer?"

Lu Yongchang said with a smile, "Pretty much, but I made some modifications to make it more suitable for processing semi-permeable materials."

With that, he strode toward the cleanroom set up next to the laboratory.

……

In the cleanroom.

A machine similar to a silicon wafer ion implanter sits quietly in the center of the cleanroom.

Lu Yongchang and Mo Zeyang, dressed in cleanroom suits, slowly walked into the cleanroom.

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

"professor?"

"Shall we start the experiment now?"

Lü Yongchang nodded noncommittally: "Of course."

"We're not from Proxima Centauri; naturally, the sooner we master this crucial technology, the better!"

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

Even though it's a thin slice, it still appears black and light gray to the outside world.

The reason is simple: semi-transparent materials with high purity do not have high light transmittance.

Even on the side that allows light to pass through, without direct strong light, it appears hazy and gray.

Lü Yongchang quickly placed the semi-permeable material into the ion implanter.

"Zero, start the ion implanter."

A slight buzzing sound followed.

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

The accelerator then started.

Specific ions are accelerated by an electric field and bombarded directly towards the thin, semi-permeable sheet!

With zero-precision control, these ions penetrate the material pores of the semi-permeable body at just the right speed and then combine perfectly with it!

Time passed by, second by second.

The buzzing sound gradually weakened.

"Professor, ion implantation is complete."

A zero-point alert sounded.

Lu Yongchang held his breath slightly, stepped forward, and opened the hatch of the ion implanter.

A thin, black sheet-like substance lay quietly in front of him.

He carefully picked it up and turned it over.

suddenly see the light!

It's like a sheet of transparent glass!

The semi-transparent body, which had been injected with a large number of impurities, revealed its true form at this moment!
