Metal: Metal refers to a substance with high conductivity. In metals al the charge carriers are aligned in particular direction so that the flow of charge carriers contribute the current. In metals there is no energy gap between valence band and conduction band.
Semi Conductor: Semi conductor refers to substance in which charge carriers are aligned in random sense providing sufficient field we can make charge carriers to align in one direction . There is a small energy gap between conduction band and valence band.

Why geranium is known semi conductors?
A geranium is a flower, and not a semiconductor. The element Germanium, however, is a semiconductor, which means it has an electrical conductivity somewhere between that of a metal and an insulator.
What is c2mos?
Clocked Complementary Metal-Oxide-Semiconductor
Difference between gunn diode and pin diode?
gunn diode is transfered electron device & PIN diode is semiconductor device
What can increase the voltage difference between a metal electrode and a solution?
If electrons are left behind in metal this will increase the voltage difference between a metal electrode and a solution. Also if the solution becomes more positive this will cause an increase.
Difference between a semiconductor and insulator?
The difference among Metal,Semiconductor and Insulator is written bellow-1.Metal:Substances through which electricity can pass easily is called Metal.1.Semiconductor:Substance which conductivity lies between Metal and Insulator are called Semiconductor.1.Insulator:Substances through which electricity can not pass easily are called Insulator.
What is the difference between metal and semiconductor?
A semiconductor's resistivity decreases with increasing temperature. A metal's resistivity increases with increasing temperature.
Is sodium a semiconductor?
It is a semiconductor.
What are the differences between metal semiconductor and insulator?
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.
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.
What is the difference between semiconductor and electronics?
A semiconductor is a device which is neither a Insulator nor a conductor. They behave like one in the right conditions.
CMOS full form?
Complementary metal-oxide semiconductor

What does cmo stand for?
It stands for: Complementary Metal Oxide Semiconductor
Is tungsten a semiconductor?
No, tungsten is not a semiconductor. Tungsten is a metal known for its high melting point and resistance to corrosion. Semiconductors are materials that have conductivity between that of a conductor and an insulator, like silicon or germanium.
What is difference in seebeck effect by using metal and semiconductor?
Seebeck effect is a compact needle. This is what makes the compose work right.
Is gold a semiconductor?
No, gold is not a semiconductor. Gold is a metal and is known for its excellent electrical conductivity, unlike semiconductors which have properties that fall between those of conductors and insulators.
What is silicon an alkali metal alkaline-earth metal transition metal or a semiconductor?
Silicon is a semiconductor. It is widely used in electronic devices due to its semiconducting properties, which allow it to be either a conductor or an insulator depending on the conditions. Silicon is not classified as an alkali metal, alkaline-earth metal, or transition metal.
