What else can I help you with?
What will happen when doped semiconductor is heated will its conductivity increase or decrease?
Doping a semiconductor means to introduce impurities to the semiconductor in order to alter it. For the most part, doping a semiconductor increases its conductivity.
What is the process of adding some impurities to semiconductor material?
Its called doping.
What can be viva question from the transistor characteristics in common emitter?
Transistor Characteristics1) What is transistor? what are the types of transistors?Ans: Transistor is a three terminal semiconductor device.There are two types of semiconductor i.e,. n-p-n and p-n-p.2) Define n-type and p-type semiconductors.Ans: If an intrinsic semiconductoris doped with pentavalent impurity. Then it is called n-type semiconductors.If it is doped with trivalent impurity then it is called p-type semiconductor.3) What is doping?Ans: Adding trivalent or pentavalent impurity to an intrinsic semiconductor is called doping.4. What are three basic transistor connection modes? Which mode is most preferred? Why?Ans: Common-Emitter, Common-Base & Common-Collector connections.CE mode is most preferred because CE modes gives Highest voltage gain.5. Define current amplification factor of a transistor?Ans: It is defined as ratio of change in collector current to change in base current.7. What is the biasing rule of transistor?Ans: Emitter base junction should be forward biased and collector base junction should be reversed biased.8. What is semiconductor?Ans: Semiconductor is a substance which has the resistivity in between that of conductor and insulator. semiconductor has negative temperature coefficient of resistance.9) Which are the commonly used semiconductors?Ans: Germanium & Silicon
How the breakdown voltage of a particular diode can be controlled?
The breakdown voltage of a diode, such as a Zener diode, can be controlled by adjusting its doping concentration during the manufacturing process. By increasing the doping concentration, the breakdown voltage decreases, and vice versa. This allows for precise control over the voltage at which the diode begins to conduct in the reverse-biased direction. Additionally, the physical size and structure of the diode can also impact its breakdown voltage characteristics.
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.
Use hexavalent or divalent impurity in diode?
Called "doping" forget specifics--studied long ag
What do you call of a semiconductor decreases while doping increases?
Impurity
What is mean by doping?
Doping is a process of adding some impurity in pure material or pure semiconductor.
Is it possible to make a semiconductor by adding hexavalent or divalent impurity?
Yes, it is possible to make such semiconductors.Semiconductors made from group III and V elements use hexavalent or divalent impurities.Example of such semiconductors are Aluminium Phosphide, Aluminium Arsenide, Gallium Arsenide, Gallium Nitride.In these cases,Donor atoms are Selenium, Tellurium, Silicon, Germanium andAcceptor atoms are Beryllium, Zinc, Cadmium, Silicon, Germanium
How the n type and p type semiconductor is joint without adding any impurity?
doping
What is doping in conductor?
The process of adding suitable impurities in the intrinsic semiconductor is called doping. The impurity added to the intrinsic semiconductor to increase its conductivity is called dopant. There are some methods of doping in case of a conductor.impurity atoms can be added to the intrinsic semiconductor in different ways discussed below:A very small quantity of impurity atoms is made by diffusing into the high purity molten material such as germanium when the crystal is grown out of melt.Impurity atoms can also be added into the intrinsic semiconductor by heating it in the environment having impurity atoms.Impurity atoms can also be added into the intrinsic semiconductor by bombarding it with the impurity atoms.
What effect do added impurities have on semiconductor conductivity?
It is called as DOPING. Doping is the process in which you add an impurity to a pure semiconductor to increase its conductivity. While doping is done, crystal structure of semiconductor is not disturbed.
What is mean by doping procesess?
Doping is the intentional introduction of impurities into a semiconductor material to alter its electrical properties. This process can change the conductivity of the material, allowing it to be used in the production of electronic devices such as transistors and diodes. Different types of doping, such as n-type (donor) and p-type (acceptor) doping, can create regions of positive or negative charge within the material.
What will happen when doped semiconductor is heated will its conductivity increase or decrease?
Doping a semiconductor means to introduce impurities to the semiconductor in order to alter it. For the most part, doping a semiconductor increases its conductivity.
What is doping in chemistry?
Addition of small amount of foreign impurity in the host crystal is known as doping. It increases the electrical conductivity.
Will a semiconductor remain electrically neutral after doping?
Yes
What kind of semiconductor is produced by adding indium in semiconductor crystals?
it is metal.. so not used for doping.
