Question

Electrical Conductivity Determination for Intrinsic Silicon at 150°C Cakulate the electrical conductivity of intrinsic silicon at 50 degrees * C C.100 100^ C 200^ C and plot the conductivity that you have found versus temperature 300 degrees * C

Answer 1

for 150^oC the values considered as standard as an example

at 150^oC = 273 + 150 = 423 K

n_i value for silicon is 4 x 10¹⁹ /m³

mobility of electron is _e = 0.06 m²/V-s

mobility of hole is _h = 0.022 m²/V-s

e = 1.6 x 10^-19 C

using equation for conductivity is = n_i e ( _e + _h )

= 4 x 10¹⁹ x 1.6 x 10^-19 x ( 0.06 + 0.022 )

= 0.52 / -m

but remaining in the problem of 50^oC , 100^oC , 200^oC , 300^oC

for these electrical mobility vs temperature graph needed.

if you graph calculate as above. then go for plotting graph.
