ZnO has an n-type character because of presence of nonstoichiometry that is absence of elemental composition that can be represented by a ratio of well-defined natural numbers.This n-type behaviour is due to point defects like vacancies and interstitials in the ionic crystal. An alternate reason presented , based on theoretical calculations is the unintentional substitutional hydrogen impurities in the compound.

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.
When silicon is doped with phosphorous what type of semiconductor results?
it would be a n-type semiconductor because phosphorus has more valence electrons than silicon does.
Why CdS is always n type semiconductor?
CdS is considered as n-type semiconductor because of the deficiency of sulfur. This creates vacancies with a high electron affinity and causes CdS to acquire electrons easily.
Is silicon a extrinsic or intrinsic semiconductor?
silicon is intrinsic semiconductor until we add some impurities in it. the impurities are either of group 3 called acceptors which make p type or of group 5 called donors which make n type semiconductor.
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.
How are N-type semiconductor used in semiconductor diode?
p-type semiconductor is obtained by carrying out a process of doping that is by adding a certain type of atoms to the semiconductor in order to increase the number of the free charge carriers.

What is an explanation of n-type and p-type semiconductors?
In n-type semiconductor, electricity is conducted by NEGATIVE charges (electrons). In a p-type semiconductor, electricity is conducted by POSITIVE charges (holes).
What are the 2 types of semiconductor devices?
N- Type and P- Type :)
What is term for a semiconductor that contains extra electrons?
N-type semiconductor contains extra electrons.
What is abbreviation NMOS?
N is the type of semiconductor, MOS refers to Metal Oxide Semiconductor device.
How is p type semiconductor formed?
p-type or n-type semiconductor alone is of very limited use in chips -- you can only make a thin-film resistor or parallel-plate capacitor with it. You also need the opposite type, the n-type semiconductor, to make junction diodes and MOS or bipolar transistors, which are essential components in an integrated circuit. ================================
How do you construct an n type semiconductor?
An n-type semiconductor is formed by doping a pure semiconductor (silicon or germanium, for example) with atoms of a Group V element, typically phosphorus or arsenic. The dopant may be introduced when the crystal is formed or later, by diffusion or ion implantation.
What is the ionization energy of an electron for an N-type semiconductor?
0.31eV
