Hi,
Apologies if this has been asked before, I performed a search but didn't find much!
Working on a textbook of semiconductor device physics, and have come across a formula for the thermal velocity of a hole/electron.
It's listed as Vth = √3kT/m*
Where m* is the effective mass.
Now entering the data for a piece of n-type silicon as follows:
k = 1.38x10^-23 JK-1
T = 300K
m* = 1.18Mo
I work this out to be 1.02x10^-10, however the textbook answer is 1.08x10^5, which is nowhere near.
Am I doing something wrong with the units or is something else off? I appreciate any help.
Thanks,
Lee
