What is the term for a semiconductor that is missing electrons?
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
What is majority carrier in p type semiconductor?
electron
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.
Can you dope a semiconductor with holes instead of electrons?
Doping with Group III elements, which are missing the fourth valence electron, creates "broken bonds" (holes) in the silicon lattice that are free to move. The result is an electrically conductive p-type semiconductor.
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.

What is the ionization energy of an electron for an N-type semiconductor?
0.31eV
Why p type semiconductor has majority charge carrier as hole?
The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.
Is a semiconductor a type of chemical?
Everything that exists in the world except for a light ray or an electrical discharge such as lightening is a chemical! A semiconductor is a type of chemical. It is made from elements with valences of 3, 4, or 5.
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.
What is the potential difference between electron pair?
Type your answer here...
Which type of electron emmission exists in GM Counter?
Secondary emmission
What is meant by intrinsic semiconductor?
Semiconductor in pure form (i.e. without doping) is called intrinsic or i-type semiconductor. The no of charge carrier in this case is determined by the materials itself only and not by the impurities. In an intrinsic semiconductor number of excited free electron is equal to the number of holes.
Do semiconductor holes have mass?
no!!!!! holes in semiconductor have no mass! the conventional way to represent holes as positively charged so there should be a question in our mind that they should have some mass,as proton, the only positively charged particle have mass,but it hasn't.actually the electrons are carrying charge in everywhere,the opposite direction of flow of current considered as the direction of conventional current, In the semiconductor also only electron carry charges,so the excessiveness of electron defined a semiconductor as n-type,or donor type(due to doping,i.e.,mixing some impurities with the semiconductor and make the semiconductor to make covalent bond with that element).and where the semiconductor is doped with some element of having only three electrons at the valence cell,the covalent bond have a shortage of electrons to complete the total covalent bond,so the semiconductor become available to add another electron to compete the covalent bond.and hence they are called p-type or acceptor type.so hole is nothing but a convention to denote this lack of electron,i.e.,lack of negative charge and it seems like the semiconductor have a positive charge that balance the electron.so the hole must not have any mass. electron have a mass-1.6*10^-19 kg
