What is forward bias current in semiconductor?
I think its related to junction of two dissimilar semiconductor (or semiconductor and metal) and not only a semiconductor. well when two opposite nature semiconductor (hetero or homo) are joined to form a junctions they allow the flow of current in one direction while blocks it in other direction. The applied bias V which will cause the current flow is called forward bias and the current flowing through the junction forward bias current.
What is light activated SCR?
A light-driven semiconductor device that prevents current flow in either direction until it receives a signal.
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.
Is copper a conductor and a semiconductor?
Copper is a conductor but not a semiconductor.
How do semiconductor differ from conductor and insulators?
SemiConductor = Kind-of-conducts.Really! By applying electricity to the conducting material (usually in a transistor or Integrated chip) the conduction rate of the material changes. This allows you to change the flow of electricity through the semiconductor by using a second smaller control voltage.This is the basis of most electrical components.Conductors(made out of materials that are not semi-conductors) fully allow electricity to flow through it.Insulators (Non-Conductors)completely block the flow of electricity.
What are the two types of current flow in a semiconductor?
Currents in a semiconductor are carried by the motion of electrons or of "holes", which are areas of localized electron deficiency.
What is baising in electronic circuits?
Biasing means providing a voltage that overcomes or restricts the flow of carrier in semiconductor. No current will flow when any semiconductor is ubiased
What is a discrete semiconductor?
A discrete semiconductor is an individual circuit that performs a single function affecting the flow of electrical current.
What are semiconductor memory and what are its type?
what is a semiconductor material? what are its main types, explain each type
What types of products are manufactured by semiconductor companies?
Semiconductor companies design and manufacture primarily two types of products: integrated circuits (ICs) and discrete devices.
A contains several types of semiconductor devices?
calculator

What are the different types of semiconductor?
Transistor Diode Resistor Capacitor
How are N-type semiconductor used in semiconductor diode?
p-type semiconductor is obtained by carrying out a process of doping that is by adding a certain type of atoms to the semiconductor in order to increase the number of the free charge carriers.
What is the term for material that is treated to slow electricity through a circuit without completely inhibiting it?
A resistor or a semiconductor, depending on the design and function. Resistors inhibit current flow, while semiconductors control current flow (transistors are an example of semiconductor devices).
What are the 2 types of semiconductor devices?
N- Type and P- Type :)
What semiconductor allows current to flow in one direction?
That is a DIODE, which can be of any of these types:P-N junction (shown above)point contactschottky barrier (i.e. metal-semiconductor junction)
