Sources of Color: Doped semiconductors

The mechanism that creates color in doped or activated semiconductors is much the same as that in pure semiconductors—energy bands and the resulting size of the band gap determine the resulting color. However, the difference is that the color is no longer a fundamental aspect of the material itself, but a result of impurities. Light emitting diodes (LEDs) are almost always the result of doped semiconductors, with materials mixed in different quantities to get the desired colors. (Gallium, arsenic, and phosphorus are common dopants/elements.) The color of yellow and blue diamond are caused by similar impurity/dopant atoms.

What Are Vacuum Diodes?

A vacuum diode is an electronic component that uses the flow of electrons in a vacuum environment to achieve current rectification and amplification. It consists of two basic parts: a cathode and an anode. The cathode is heated to release electrons, which then move through the vacuum and are attracted to the anode, forming a current.

Why do MOS tubes need to be connected in parallel with a diode?

MOS has a body diode connected in parallel between the D and S poles, so why is this diode connected in parallel?

This starts with the process and structure of MOS. The diode is composed of a pair of PN junctions. The P-type region corresponds to the positive pole of the diode, the N-type region corresponds to the negative pole of the diode, and the PN junction is in the middle. SiO2 in the MOS tube itself is not conductive, so the driving pole G basically does not carry current.

In addition to the three poles D, G, and S, there is also an intermediate pole, which is connected to the S pole, so in the circuit symbol of MOS, the arrow pointing to the channel N channel inside the MOS is connected to the S pole.

In addition, the drain of the N-type region is connected to the middle P-type region and then to the source, which just forms a diode structure, so a diode is connected in parallel in the MOS symbol.

What is the use of this body diode?

In some scenarios, such as battery protection, after the lithium battery is over-discharged, the protection function will be turned on: turn off the discharge MOS. When the charger is plugged in, the MOS body diode is used to make the circuit conductive and the system work normally. However, in some scenarios, the existence of this diode is undesirable because it may cause leakage between the S pole and the D pole.
