Because at this temperature the covalent bond become stronger which can't be broken by applying external forces(voltage).
room temperature instrinsic s.c as a conducter
There are no free electrons and holes in a pure semiconductor at 0k.
This solid is a semiconductor.
" semiconductor "
A semiconductor is a material that has resistance in between a conductor and an insulator. This means that it can conduct electricity under certain conditions but acts as an insulator under others. Examples include silicon and germanium.
No, phosphorus is not an insulator. It is a semiconductor, which means it has electrical conductivity in between that of a conductor and an insulator.
Its an Insulator
Germanium is a semiconductor
Yes, a semiconductor can be made to behave as a conductor or an insulator by controlling the amount of impurities added to it. Adding impurities through a process called doping can change the conductivity of the semiconductor material, making it act like a conductor or an insulator.
Diode is a semiconductor material. so it act as insulator also.
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.
semiconductor is intermediate between conductor and non conductor of electricity
