What effect do added impurities have on semiconductor conductivity?

It is called as DOPING. Doping is the process in which you add an impurity to a pure semiconductor to increase its conductivity. While doping is done, crystal structure of semiconductor is not disturbed.


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.


Warming up your body temperature while cooling down your body temperature. A.increases decreases B.decreases increases C.regulates restricts D.stimulates stops?

increases, decreases


What happens to the velocity as the height increases?

As height increases, the velocity generally decreases due to the effect of gravity. This is because potential energy increases while kinetic energy decreases, resulting in a slower velocity.


What are the differences between metal semiconductor and insulator?

Metal is a good conductor of electricity due to the presence of free electrons, while semiconductor has conductivity in between metal and insulator and its conductivity can be controlled by doping. Insulator has very low conductivity as it lacks free electrons for conduction.


What decreases an asset account credt or debit?

Assets has debit balance as normal balance so debit balance increases it while credit balance decreases it.


When the freuency of a wave traveling at constant speed increases what decreases?

As the frequency of a wave increases while traveling at a constant speed, the wavelength decreases. This is because the speed of a wave is determined by the product of its frequency and wavelength, so if one increases while the other remains constant, the other must decrease to maintain a constant speed.


When supply decreases and demand remains the same equilibrium price will..and equilibrium quantity will..?

Price decreases while the quantity increases...i think!!!I am improving this answer because this guy's answer is wrong. If supply decreases while demand remains the same price will go up while quantity goes down.


Why do extrinsic semiconductor behave as good conductors?

we know that relation in semiconductor is conductivity proportional to temp especially in extrinsic semiconductor holes or electrons are charge carriers . in extrinsic semiconductor when temp is increased then the energy of charge carriers also increases. now kinetic energy equall to [ (1/2) m v^2 ] in this M is constant this implies energy prop to square of velocity therefore if conductivity of charge carriers increases while increasing of temperature
