What is the effect of temperature on transistor?
conductivity of semiconductors increases with increase in temperature as breakdown of covalent bonds take place in the semiconductor due to increase in temp but more & more increase in the temp may result in the breakdown or damage of the semiconductor which results in the decrease in conductivity of semiconductor
Why can a semiconductor measure temperature?
Semiconductor resistance depends on temperature. So, you can use a shunt resistor to measure semiconductor voltage with a given current and, then, obtain temperature.
What is meant by operating temperature of semiconductor?
The operating temperature of a semiconductor is the temperature at which a semiconductors exhibits the properties of a normal conductor.
Hall effect in semiconductor?
Hall effect
What is the effect of temperature on hall coefficient of a lightly doped semiconductor?
hall coefficient of a lightly doped semiconductor will decrease with increase in temp as hall coefficient is inversely proportional to number density of charge carriers.
What is the difference between metal and semiconductor?
A semiconductor's resistivity decreases with increasing temperature. A metal's resistivity increases with increasing temperature.
What is the effect of temperature on an intrinsic semiconductor?
An intrinsic semiconductor is basically a pure semiconductor, though some might argue that a small amount of doping can still yield an intrinsic semiconductor. In the crystal structure of this material, there are very few electrons crossing the band gap into the conduction band, and this stuff doesn't want to conduct much current. But as temperature increases, more electron-hole pairs will appear as electrons jump that band gap and take up places in the conduction band. And if you guessed that increasing temperature will permit the intrinsic semiconductor to conduct current flow a bit better, you'd be right. The intrinsic semiconductor has a positive temperature coefficient. More heat, more conduction under the same conditions.
What is the temperature coefficient of extrinsic semiconductor?
positive
How does the electrical conductivity of a semiconductor vary with temperature?
The electrical conductivity of a semiconductor typically increases with temperature. As the temperature rises, more charge carriers are generated in the semiconductor, leading to higher conductivity. This is due to the increased thermal energy that excites electrons into the conduction band.
How intrinsic semiconductor can be made into extrinsic semiconductor?
at higher values of temperature the intrinsic carrier concentration become comparable to or greater than doping concentration in extrinsic semiconductors. thus majority and minority carrier concentration increases with increase in temperature and it behaves like intrinsic semiconductor.
How does temperature effect semiconductors?
Firstly a general rule: Too hot fries anything.(and lesser important: too cold and you get superconduction) Resistors For normal resistors: as temperature increases, the electrical resistance decreases.Though specially made heat sensitive resistors with the opposit effect (for temperature measurements) do exist.
