The  electrical  resistance  of  an  electrical  conductor  is  the  opposition  to  the  passage  of  an  electric
current through that conductor; the inverse quantity is electrical conductance.The
semiconductor materials  become  a conductor of current.A
pure  semiconductor  material  at  absolute  zero  has  the  characteristics  of  an  insulator  because  all
electrons are in the valence sector while the conduction sector is empty.Therefore, in semiconductors, the  resistance
decreases with the increase in temperature.
