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

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.

No.


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.


What is the difference between absolute temperature scale and kelvin scale urgent I am convinced that there is a difference?

The Kelvin scale is an absolute temperature scale where 0K represents absolute zero. The absolute temperature scale refers to any temperature scale that starts at absolute zero, such as the Kelvin scale. So, the Kelvin scale is a specific type of absolute temperature scale.


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.


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.


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.


What is absoulte temperature?

Absolute temperature is a temperature measured on a scale that starts at absolute zero, where particles have minimal motion. The most common absolute temperature scale is the Kelvin scale, where 0 K is equivalent to -273.15 degrees Celsius. Absolute temperature is used in thermodynamics and physics to describe the energy of a system.


What are the units of absolute temperature?

If you mean unit for absolute temperature, the Kelvin is usually used.
