P-Type Material

P-Type Material P-type material is produced when the dopant that is introduced is from Group III. Group III elements have only 3 valence electrons and therefore there is an electron missing. This creates a hole (h+), or a positive charge that can move around in the material. Commonly used Group III dopants are aluminum, boron, and gallium.The 2D diagram to the left shows the hole that will be present when a Group III dopant is introduced to a material such as silicon. This hole is quite mobile in the same way the extra electron is mobile in a n-type material.

Relationship Among Energy Units

The Energy whether possessed by an electrical system or mechanical system or thermal system has the same thing in common i.e., it can do some work. Therefore, mechanical,electrical and thermal energies must have the same unit. This is amply established by the fact that there exists a definite relationship among the units assigned to these energies. It will be seen that these units are related to each other by some constant. 1. Electrical To mechanical 1kWh = 1 kW x 1 hr = 1000 watts x 3600 seconds = 36 x 10 5 watt-sec. or Joules ...

Diode Characteristics

Diode Characteristics A power diode is a two-terminal pn junction device.When anode is positive with respect to the cathode,the diode is said to be forward biased and it conducts. When diode conducts it has a small forward drop voltage (which depends on manufacturing process and junction temperature).
