    Intrinsic current of the diode, what is its current?

    My doubt is why I can't find the same value that you got using this formula. I'm having some difficulty finding the diode's intrinsic current, I applied some formulas, but I don't know if it's correct. Could anyone tell me if this is correct or why it is wrong? If this is right, I would like to...

    How is the dry process using porous silicon?

    I'm having trouble finding in the literature specifically about the porous silicon process using the dry method instead of the more common wet method that is used. wet process: Using porous silicon to promote wet thermal oxidation uses the process electrochemically will allow water molecules to...

    PIN diode - what setting to detect the frequency?

    My question regarding the use of the pin photo diode, I could not understand what would be the best configuration using an integrator operational amplifier for frequency detection if it is the photo conductor or photovoltaic.

    [SOLVED] transconductance photodiode?

    Hello, I'm having trouble finding a theoretical explanation about the transconductance photodiode behavior, the materials I find on the internet they talk about the connections, but not the behavior, in case someone could insert material or write here with the source please.

    What is the dielectric value of the mosfet gate when hiring acceptors?

    Hello, I'm having trouble finding the value of the right concentrators that are on the gate of the gate (SiO2 as gate dielectric and P-type substrate [NA=?]) Could someone indicate a material to show a usual value?

    What is Electromagnetic Cross Section? (shock section)

    Hello, I have a question regarding the manufacturing process of electronic components in the case of the silicon deposition and corrosion process. My biggest doubt is the behavior of the plasma interacting in the reactor, I don't know if it's correct I would like someone to help me. What I...

    Transparent crystalline silicon process Photovoltaics photonic

    I understand your argument, but actually there is the part of the transformation of the transparent crystalline Silicon send a link talking about this process facially, but I don't find the process exactly as it is manufactured as an image explaining step by step, as an example process...

    Transparent crystalline silicon process Photovoltaics photonic

    Hello, I would like an article, book or link on the manufacturing process of crystalline silicon, where the transformation of transparent crystalline silicon used in solar cell, (which is related to photonics), practically the light ends up deflecting, but not completely because there is a...

    PLASMONICS - Exercise

    Hi I'm having difficulties with the plasmonica exercise, I sell some books and scientific publications I came across that there are two or more ways to get the result but I don't know what the correct sequence is. Values: τ, γ and mainly ωp^(2). ωp^(2)= in most of the literature = Design and...

    LED Driver - Luminaire still lights up

    Guys I'm having difficulties regarding a light drive, I'll report the problem and what I did to try to solve this situation. The light driver is being placed in an LED fixture, when you clear a phase (using interrupted or forcing a phase out), the LED is lit, it stays lit very dimly. And when...

    triac optocoupler with dual output

    I want to make an application an isolate circuit with a switch. Using moc 3021 I managed to do it, but I need two. To reduce the project I need two outputs. As moc 3021 only one output. In short I would need two outputs. Each output supported 290 mA.

    triac optocoupler with dual output

    Thank you guys, but this model you passed has a very low current of 25 mA. In my case I need the output to support a current of 290 mA if it's better for me. The complicating factor is that it seems there is only this one on the internet (market/datasheet)

    triac optocoupler with dual output

    I'm having trouble finding a tric coupled photo with two independent outputs. Diode input can be the same, it is not necessary if 2 separate diodes. Someone could indicate a specific model, website or name of the component.

    The ion implantation allows for greater flexibility in obtaining doped layers?

    I know that when implementing ionic using a dopant (example aletorio boron ) in the machine that makes the ionic implantation on top of the silicon material, it ends up shooting inserted dopants on top of the silicon. I know implementing ionico has greater flexibility, particularly if shallow...

    Why is oxide not used in the CVD process in the manufacture of gate oxide in the NMOS device?

    I know that chemical vapor deposition (CVD) is a vacuum deposition method used to produce high-quality, high-performance solid materials. The process is often used in the manufacture of semiconductors to produce thin films, there are several CVD methods, such as LPCVD, PECVD etc. Depending on...
