What is a semiconductor diode and their application?
It can be either a junction or point contact diode built with semiconductor material. there are many types depending on intended usage.junction diode is produced as described in its name by forming a junction in the semiconductor by using opposite types of dopant impurities.point contact diode is produced as described in its name by taking a semiconductor base and pressing a sharp metal point on its surface.A few of the types of semiconductor diodes are: small signal, power rectifier, zener, tunnel, gunn, etc.

Is it possible to make a junction diode by pressing two pieces of n type and p type together?
No, a functioning junction diode cannot be made by placing two oppositely doped pieces of semiconductor in contact with each other. A functioning junction diode can only be created in one piece of semiconductor with oppositely doped regions in it.However if you placed the two oppositely doped pieces of semiconductor in contact with each other and HEATED them until they just began to melt and joined becoming one piece, it is possible to create a functioning junction diode this way. But this is a tricky and not very reliable way to do it, especially if you melt it just a tiny bit too much you will completely mix the two pieces and lose the doping entirely.
What is the difference between a semiconductor diode and a microwave diode?
The primary difference is that a semiconductor diode is a diode with a p-n junction, and a light-emitting diode is a special case or special type of semiconductor diode that emits light when it is forward biased.
Why the voltage drop across LED is around 2V instead of 0.7V?
the binary semiconductors used to make LEDs have forward bias voltages from 1.5V to 6V depending on color (1.5V for IR-red to 6V for blue-UV) because the bandgap voltage of the semiconductor is higher than silicon. This higher bandgap is where the photons generated get their energy from. germanium has a lower forward bias voltage of 0.2V because the bandgap voltage is lower. metal-semiconductor contacts, like point contact diodes and schottky barrier diodes, can have forward bias voltages under 0.1V
What is difference between ohmic and rectifying contact?
A p-n junction (or a metal-semiconductor junction) with rectifying behaviour is an electronic device which allows a one-way only current flow (between the two semiconductor regions, or between the metal and the semiconductor). An ohmic contact in a metal-semiconductor junction is realized by lowering the potential barrier (allowing electrons to easily migrate into the metal) and by increasing the doping levels in the semiconductor (more than 10^18 cm^-3): this way the potential barrier, that should stop electrons from migrating into the semiconductor, is confined in a very small region making it possible for electrons with low energy to pass through it (tunneling effect). This means that in a ohmic contact current can flow both ways; such a device apparently works like a resistor with a low resistance, hence the "ohmic contact" name.
What is the term for an electronic component of two layers of semiconductor?
junction diodeThere are two other ways of making a simple solid state diode:point contact diode, one piece of semiconductor with a sharp metal needle point touching itmetal-semiconductor diode, a layer of metal over a layer of semiconductor

What are the definition of electrodes?
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum).

What is meant by flat band potential?
Flat band potential refers to the electrochemical potential of a semiconductor in contact with an electrolyte when the bands of the semiconductor are flat across the interface. It signifies the point where the Fermi level of the semiconductor matches the redox potential of the electrolyte, leading to no net flow of charge across the interface. It is a key parameter in understanding semiconductor-electrolyte interfaces in electrochemical reactions.
What is the relationship between Reflux Ratio and the number of contact stages?
The reflux ratio effects the positioning of the rectifying section operating line ( Xd/(Rmin+1) this equation gives the point at which the rectifying operating line intersects the y-axis ). therefore an infinte value for the reflux ratio will give the very minimum number of stages required. SO basically the relationship is, the higher the reflux ratio, the less stages needed. hope this answers your question.
What is a Shockley diode?
An ordinary semiconductor diode uses a P-N junction, but when reverse biased it takes a period of time to remove the current carriers from that junction to create the depletion region that blocks reverse conduction. A Shockley diode instead uses a P semiconductor-metal junction, which removes the current carriers much faster from the semiconductor allowing the device to switch much faster. It also has a much lower forward bias voltage than an ordinary diode. In many ways it is similar to the previous point contact diodes (a piece of semiconductor like galena or germanium with a metal "cat's whisker" point contact) in operation, but is more reliable and easier to mass produce.
What is bonding wire used for?
Bonding wire is used in semiconductor packaging to electrically connect the chip to the package or substrate. It is thin and made of materials such as gold, aluminum, or copper. Bonding wire plays a crucial role in ensuring proper electrical contact and signal transmission within the semiconductor device.
