What is a Transistor
A transistor is a solid state semiconductor device which can be used for numerous purposes including signal modulation, signal amplification, voltage stabilization, and many other applications.

Transistors act like a variable valve which, based on its input current (BJT) or input voltage (FET), allow a precise amount of current to flow through it ....etc

CONDUCTIVITY ,FERMI LEVEL ,
MEAN FREE PATH &
RELAXATION TIME
FOR TYPICAL MONO-VALENT METALS
IS SHOWN IN TABLE

The conductivity may be obtained experimentally .
Further we can get by using eqn given below
= ( n*Qe2 * )/me --(1)
but obtained may not be accurate but we will get an idea of magnitude of . In a monovalent metal no of free e- /m3 is equals the no of atoms /m3 . From table we find that relaxation time T is of the order of 10-14 sec .Thus we can say that T is extremely small f ....etc

Removel of material by using electron beam and electrical field.
ELECTRON BEAM MACHINING :
A high velocity stream of electrons is focused on the workpiece surface to remove material by melting and vaporization
Electron beam gun accelerates a stream of electrons to 3/4 c and focused through an electromagnetic lens
Kinetic energy of beam converted to thermal energy of extremely high density, melting or vaporizing material in a very localized area
EBM must be carried out in a vacuum
MATERIAL PROCESSING BY ELECTRON BEAM:

A surface-conduction electron-emitter display (SED) is a flat panel color television technology currently being developed by a number of companies.MAny electron emitters which are nanoscopic-scale are used for energizing the colored phosphors and produce an image. Thus a SED contains a matrix of tiny cathode ray tubes and may of them forming red-green-blue (RGB) pixels. Its advantages include: high contrast ratios, wide viewing angles and very fast response times, and also the power and packing advantages of LCD are also there.

Abstract

Field emission (FE) (also known as field electron emission and electron field emission) is emission of electrons induced by an electrostatic field. The most common context is field emission from a solid surface into vacuum. However, field emission can take place from solid or liquid surfaces, into vacuum, air, a fluid, or any non-conducting or weakly conducting dielectric. The field-induced promotion of electrons from the valence to conduction band of semiconductors (the Zener effect) can also be regarded as a form of field emission ....etc
