CONDUCTIVITY σ ,FERMI LEVEL ,
MEAN FREE PATH &
RELAXATION TIME ť
FOR TYPICAL MONO-VALENT METALS
IS SHOWN IN TABLE
The conductivity σ may be obtained experimentally .
Further we can get ť by using eqn given below
σ = ( n*Qe2 *ť )/me ---------(1)
but ť obtained may not be accurate but we will get an idea of magnitude of ť . 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 ....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
