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.
What are trivalent and pentavalent impurities?
Doping is the process of adding impurity atoms to intrinsic silicon or germanium to improve the conductivity of the semiconductor. The term impurity is used to describe the doping elements. Two element types are used for doping: trivalent and pentavalent. A trivalent element is one that has three valence electrons A pentavalent element is one that has five valence electrons. When trivalent atoms are added to intrinsic semiconductors, the resulting material is called a p-type material. When pentavalent impurity atoms are used, the resulting material is called an n-type material. The most commonly used doping elements are listed below. Commonly Used Doping Elements Trivalent Impurities To make p-type Aluminum (Al) Gallium (Ga) Boron (B) Indium (In) Pentavalent Impurities To make n-type Phosphorus (P) Arsenic (As) Antimony (Sb) Bismuth (Bi)
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)
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.
What is bulk resistivity?
Bulk resistance is the ohmic resistance of the semiconductor material. The natural resistance of a "P" type or "N" type semiconductor material.
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 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.
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.
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 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.
