As temperature increases the resistance of semiconductors decreases. This means that semiconductors have a negative temperature coefficient.

Where kirchhoff's law fails?
In semiconductors, at quantum scales, at temperatures close to absolute zero...
Who defined the absolute temperature scale?
The absolute temperature scale was defined by Lord Kelvin.
What does the absolute temperature scale use as its reference temperature?
-459.67 F Which is absolute zero and that is the temperature at which all molecular activity stops.
Explain how ideas about particles can account for the absolute zero of temperature?
Absolute temperature is a thermodynamic temperature and is used as the standard temperature unit. Temperature comes from the kinetic energy of a matters particle and random motions. When motion stops, it is considered absolute zero.
How do you use absolute zero in a sentence?
Nothing moves when the temperature is at absolute zero.

What Materials have a negative temperature coefficient?
Glass, Ceramics, Semiconductors
what temperature a ferromagnetic material behaves like a paramagnetic material?
Curie 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.
Is there absolute maximum temperature like absolute zero minimum temperature?
No.
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.
Is in p type semiconductors electron hole pair is form at room temperature?
In p-type semiconductors, electron-hole pairs can be created at room temperature by thermal excitation. When a hole is created by an electron moving from the valence band to the conduction band, a corresponding electron-hole pair is formed. This process can occur due to energy supplied by thermal vibrations even at room temperature.
What is the difference between kelvin and absolute kelvin?
Kelvin is the absolute temperature - a temperature where absolute zero, the lowest temperature possible, is defined as zero. Therefore, in the phrase "absolute Kelvin", the word "absolute" seems redundant.
Is absolute temperature is same like absolute zero?
No, but they are related. Absolute zero is the coldest possible temperature. Absolute temperature is the temperature above this coldest possible temperature - i.e., how much hotter is it than the coldest theoretically possible temperature. Celsius temperature isn't absolute. It starts from the temperature of freezing water, and it needs negative numbers for anything colder than that. Fahrenheit temperature isn't absolute. It says that zero is 32 degrees colder than freezing water, and it needs negative numbers for anything colder than that. Absolute temperature starts from absolute zero. Nothing is colder than that, so absolute temperature is never a negative number.
Who defined the absolute temperature scale?
The absolute temperature scale was defined by Lord Kelvin.
What are the units of absolute temperature?
If you mean unit for absolute temperature, the Kelvin is usually used.
The kelvin scale is used to measure what?
The Kelvin scale is used to measure absolute temperature, i.e., temperature from absolute zero. The way it is defined, there are no negative temperatures on the Kelvin scale.The Kelvin scale is used to measure absolute temperature, i.e., temperature from absolute zero.
