Why The Conductivity Of Germanium Is More Than That Of Silicon At Room Temperature? Answer: The potential Barrier of Silicon is more compared to Germanium which makes Ge more conductive as compared to Si. … At room temperature, Silicon crystal has fewer free electrons than Germanium crystal. This implies that silicon will have much smaller
Why Does The Conductivity Of Semiconductors Increase As Temperature Increases? The conductivity of a semiconductor increases with increase in temperature because. both number density of carriers and relaxation time decreases but effect of decrease in relaxation time is much less than increase in number density . How does temperature affect conductivity of semiconductors? At absolute
How Does The Doping Increase The Conductivity Of Intrinsic Semiconductor? Extrinsic semiconductors are just intrinsic semiconductors that have been doped with impurity atoms (one dimensional substitutional defects in this case). Doping is the process where semiconductors increase their electrical conductivity by introducing atoms of different elements into their lattice. How does doping effect the conductivity
What Is Intrinsic And Extrinsic Materials? Intrinsic semiconductors are composed of only one kind of material. Extrinsic semiconductors are made of intrinsic semiconductors that have had other substances added to them to alter their properties (they have been doped with another element). What is the difference between intrinsic and extrinsic material? The difference between intrinsic
How Does P-type Semiconductor Increase Current? p-type semiconductors are characterized by a deficit of electrons and positive holes, which have the same effect as a surplus of positive charge. These positive holes accept electrons, rendering the semiconductor more effective at conducting current. How is conduction increased in an p type semiconductor? Conduction of a p-type
