conductivity of semiconductors increases with increase in temperature as breakdown of covalent bonds take place in the semiconductor due to increase in temp but more & more increase in the temp may result in the breakdown or damage of the semiconductor which results in the decrease in conductivity of semiconductor

Why is MOSFET called IGFET?
MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.
What is mean BFW11?
Its a Transistor used in JFET (Junction Field Effect Transistor)
Where was the transistor created?
The transistor was created by researchers at the university of Geneva. "The first patent for a field-effect transistor principle was filed in Canada... 1925. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor."
What are the factors that affect the bias stability of a transistor?
temperature
What does SK stands for SK 100 transistor?
In the transistor, first letter denotes the material and the second letter denotes about the type of device. Hence here in sk100 transistor, first letter s denotes that it is a silicon transistor and second letter k denotes that it is a hall effect device.So, sk100 is a hall effect silicon transistor....
Why CE transistor is more temperature senstive than CB transistor?
In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.

What are FETs?
Field Effect Transistor A: basically a silicon bar where the conduction is controlled by a field since there is no connection to the gate the impedance is very high
What is transistor mos?
Metal Oxide Semiconductor. Usually used when referring to a specific type of transistor which uses this type of semiconductor material: the Field Effect Transistor (FET).
What is junction temperature of the transistor?
The junction temperature is limited by the relationship between temperature and life, and the characteristics of the materials composing the transistor. Furthermore, transistors use minority carriers and thus are easily affected by temperature. In particular , if the temperature rises in a reverse-biased collector-base junction, carriers are generated without relation to the signal, the operating point shifts, and in the worst case thermal runaway occurs and the transistor becomes damaged. For this reason, the circuit must be designed so as to prevent the junction temperature from rising. Transistor deterioration occurs quickly when the junction temperature rises.
What is the measure of how a transistor reacts to changes in temperature?
The thermal voltage.
Is Vcc notation used only in a transistor circuit?
Vcc is used in bipolar transistor circuitsVdd is used in field effect transistor circuitsB+ is used in vacuum tube circuits
