pn junctions

PN Junction diode formed

• Special fabrication technique of combining P and N -type material

• Pushing P and N- type material towards

• Welding of P and N type material

Majority carriers of P type materials

• Neutrons

• Electrons

• Protons

• Holes

The depletion region contains

• Electrons

• Holes

• Immobilized charge carriers

• Sea of electrons

Diode 

•  allows current to flow in one direction
•  allows current to flow in two directions
• is a resistor

In the forward bias arrangement of a p-n junction diode,

• the n-end is connected to the positive terminal of the battery

• the p-end is connected to the positive terminal of the battery

• the direction of current is from n-end to p-end in the diode

• the p-end is connected to the negative terminal of the battery

Materials which can conduct electricity better than insulator,but not as well as conductors. This is the definition of

• diode

• semiconductor

• conductor

• insulator

• superconductor

Doping of Semiconductors

• materials which can conduct electricity better than insulator, but not as well as conductors.

• The process of adding of a certain amount of specific impurities atoms in the pure semiconductor.

• when 4 electrons in outermost orbit.

The majority carriers in N-type silicon are called _________________

• Neutron

• Proton

• Electron

• Hole

The current in a semiconductor is produced by

• electron only

• holes only

• negative ions

• both electrons and holes

What is the most common semiconductor material used for producing integrated circuits

• Quartz

• Silicon

• Diamond
