How are N type semiconductors formed?
N-type semiconductors are a type of extrinsic semiconductor where the dopant atoms (donors) are capable of providing extra conduction electrons to the host material (e.g. phosphorusin silicon). This creates an excess of negative (n-type) electron charge carriers.
What is the net charge on n type n p type?
n-type and p type has net no charge because the number of proton and electron remain same in a crystal. (shahbaz)
How does motion of electron in n type substance differes from motion of hole in p type substance?
Electrons constitute electronic current in n-type substance and holes constitute conventional current in p-type substance.The motion of electron in a n-type substance is opposite to that of holes in a p-type substance.
Why conductivity of n-type semiconductors is greater than p-type semiconductors?
because in n-type there is a real movement of a free negative charge(electrones not positive holes)
Diffrentiate n-type and p-type?
When pentavalent impurity is added to pure semiconductor, it is known as N-Type semiconductor. In N-type semiconductor electrons are majority carriers where as holes are minority carriers. impurities such as Arsenic, antimony are added. When trivalent impurity is added to pure semiconductor, it is know as P-type semiconductor. In P-type semiconductor holes are majority carriers whereas electrons are minority carriers. Impurities such as indium, galium are added.
How are P- and N-type materials made?
how can i make p type n type material
What you understand by the term intrinsic semiconductor and how an intrinsic semiconductor is turned into either a p type or an n type material?
An intransic material is a material that have been used in doping process.There are two type of intrinsic material n type and p type.
Use of p-n type material?
Diodes.
How are transistors made?
when p-type and n-type semiconductor materials are joined p-n junction diode is formed
What material is a diode made of?
A semiconductor diode is made of two semiconductore mterials type "p" and type "n" fused together, these two are connected to two leads, the all that is encased in epoxy.
Do a slab of n type material carry a net negative charge?
No. The "n" and "p" does not refer to the negative or positive charge, but to the fact that there are atoms that can easily "donate" electrons (n-type), or atoms that can easily "accept" electrons (p-type).
What is forward biased p-n junction?
A forward biased p-n junction is when an external voltage is applied in such a way that the positive terminal is connected to the p-type material and the negative terminal is connected to the n-type material. This reduces the barrier potential, allowing current to flow through the junction.
What is a description of Simple P-N junction diode?
The junction formed by the combination of a P- type & N-Type material in known as PN jn diode. It is used as a switch as well as a rectifier.
Is p-type material positively charged?
The net charge on n-type and p-type meterials is zero because the r formed by the combination of diferent chemists...
What is p type silicon substrate?
Wafers are formed of highly pure defect-free single crystalline material. Donor impurity atoms, can be added to the molten intrinsic material changing it into n-type or p-type extrinsic semiconductor.
What is formed when part of a material is doped n-type and part of it is p-type?
if the two parts are next to each other, a junction. if not, nothing.
Why silicon crystal are suitable for making a diode and have a junction of P-type and N-type material?
you can find silicon and germanium materials has 4 valence electrons. This makes them to be useful to make p type and n type materials easily.They are very cheap compare to others.
