What is HEMT?
I;m pretty sure HEMT is a medical word. So go to Web- Md to find out the definition. Or Websters Online. HEMT(High Electron Mobility Transistor) is a type of field effect transistor, it improves electron mobility using ternary semiconductors.
Electron mobility of intrinsic Si semi conductor?
1450 at 300k
Mobility in terms of hall effects?
Mobility means how quickly an electron can move through a metal or semiconductor when an electric field is applied.
What is M.U.?
mu is the mobility(electrons or holes ) of the current carriers in the semiconductors. mu-e being electron mobility and mu-a being the hole mobility.
What do you mean by drift velocity and mobility of a free electron?
Drift velocity Vd = acceleration x relaxation time So Vd = (E e / m) * t Now Vd / E is defined as the drift velocity per unit electric field and known to be mobility of free electron Hence mobility = (e/m) x t Thus mobility will be different in different material as it depends on relaxation time. e/m is the specific charge of electron which is a constant value equals to 1.759 x 1011
How do you Define the mobilty of charge carrier?
I am assuming the charge carries are electron and hole in an semiconductor. the mobility of charge carriers can be understood as the easy with which the carrier can move in a semiconductor. the mobility depends on many factors like the semiconductor material (because of the crystal structure), semiconductor specimen temperature, the effective mass of carrier, the applied electric field across the specimen. in general if we compare the mobility of electron with hole in a silicon semiconductor, the mobility values at room temperature is some thing around 1350 cm^2 per volt sec and 450 cm^2 per volt sec for electron and holes. that is mobility of electron is 2-3 time more than the holes in silicon.
Why is it that on increasing the current heat dissipation increase?
because when current is incresing then mobility of an eletron is also incesed so on collesion with an electron to another electron heat is more dissipated.
Where can I compare prices for mobility scooters?
You can find reviews and prce information on mobility scooters at www.SpinLife.com
Where can one find information on MTS Mobility?
There are several different online sources where one can information about MTS Mobility. Compare Cellular, Next Mobility and MTS Mobility are websites which provide information about this subject.
What units are the electron mobility measured in?
Amps or AmperesYou would use the unit of electrical current - the ampere.amperesThe Ampere.1 Ampere = around 6,241,000,000,000,000,000 electrons per second (6.241 x 1018)passing a point in the conductor.
Where can someone find a cheap mobility scooter?
A person can find a cheap mobility scooter by going onto websites such as Craigslist and searching for the price range that they are involved in to find one.
Why mobility of holes is greater than mobility of electron?
electrons have less effective size than that of holes(which actually are not real)...formula says m(mobility)=drift velocity/electric field=et/m where t is relaxation time.. so mobility is inversely proportional to mass hence e has more mobility.
