What is the Difference between elemental semiconductor and compound semiconductor?
Elemental Semiconductors: They are single elemental Semiconductors.They belong to the IV group of the Periodic Table. Example: Si,Ge,C,Sn. Compound Semiconductors: They are formed by using two or more elements.they are synthesized using elements from groups II through VI of the periodic table, e.g. from group III and V (III-V compounds) or II and VI (II-VI compounds). EXAMPLE: III-V semiconductors:GaAs, GaP, GaN, GaAlAs, InP, InSb, etc. II-VI semiconductors:CdSe, CdTe, CdHgTe, ZnS.

What is the difference between metal and semiconductor?
A semiconductor's resistivity decreases with increasing temperature. A metal's resistivity increases with increasing temperature.
What is the difference between step graded and linearly graded semiconductor p-n junction?
In step-graded the acceptor and donor concentrations in the semiconductor are constants up to the junction.In a linearly-graded junction, impurity concentration varies linearly with distance from the junction
What is difference between ohmic and rectifying contact?
A p-n junction (or a metal-semiconductor junction) with rectifying behaviour is an electronic device which allows a one-way only current flow (between the two semiconductor regions, or between the metal and the semiconductor). An ohmic contact in a metal-semiconductor junction is realized by lowering the potential barrier (allowing electrons to easily migrate into the metal) and by increasing the doping levels in the semiconductor (more than 10^18 cm^-3): this way the potential barrier, that should stop electrons from migrating into the semiconductor, is confined in a very small region making it possible for electrons with low energy to pass through it (tunneling effect). This means that in a ohmic contact current can flow both ways; such a device apparently works like a resistor with a low resistance, hence the "ohmic contact" name.
Difference between light emitting diode and laser?
LEDs, known as light emitting diodes, are comprised of two lead semiconductor light sources. Laser transmitters, also known as laser diodes are comprised of an electrically charged semiconductor laser.
Why do you use semiconductor why not conductors and insulators by changing their properties?
We use semiconductors instead of conductors and insulators by changing their properties because the properties of a semiconductor lies between that of a good insulator ant that of a good conductor. Any of the materials obtained depends on the level of doping.
