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.
The conductivity of semiconductors increases with an increase in temperature as the breakdown of covalent bonds take place in the semiconductor. If the temperature keeps rising it may result in damage to the semiconductor with a decrease in conductivity.
Heat degrades the conductivity of semiconductor's. The excessive buildup of heat can also cause permanent degradation of a semiconductor. Conduction in a semiconductor is provided by doapants which are "implanted" into the strata, heat can cause migration of these doapants into other layers in a typical "chip".
With the increase in temperature, the concentration of minority carriers starts increasing. Eventually, a temperature is reached called the critical temperature (85° C in case of germanium and 200° C in case of silicon) when the number of covalent bonds that are broken is very large and the number of holes is approximately equal to number of electrons. The extrinsic semiconductor now behaves essentially like an intrinsic semi-conductor.
As temperature increases the resistance of semiconductors decreases. This means that semiconductors have a negative temperature coefficient.
effect of temperature on elasticity
Assuming the pressure is not so great that the material fractures, it may alter thecapacitance hence behaviour of the device.
The effect of temperature on specific heat of material is referred to as specific heat capacity.
no it does not
As temperature increases the resistance of semiconductors decreases. This means that semiconductors have a negative temperature coefficient.
no, Hall Effect occurs in semiconductors
Glass, Ceramics, Semiconductors
The operating temperature of a semiconductor is the temperature at which a semiconductors exhibits the properties of a normal conductor.
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
semiconductors
Semiconductors serve as a source of electrons to form an electrical current. Semiconductors form a path for the electrons that are released by the photoelectric effect.
The Seebeck effect is a phenomenon in which a temperature difference between two dissimilar electrical conductors or semiconductors produces a voltage difference between the two substances. When heat is applied to one of the two conductors or semiconductors, heated electrons flow toward the cooler one. If the pair is connected through an electrical circuit, direct current (DC) flows through that circuit.
The materials used in the solar panels comprise of semiconductors. They are the materials that exhibit electron flow when brought at a particular temperature also known as threshold temperature. The materials comprise of Silicon, Germanium which are also referred to as semiconductors.
effect of temperature
at low temperature its forbidden gap is very large so it act as a insulater.
