it is not possible to write v = d/t but v=dx/dt and a = dv/dt then v(t) =∫a(t)dt =at + v , v is the initial velocity and the acceleration a is constant. it comes : x(t) =∫v(t)dt = 1/2 at^2 + vt + x(0), x(0) is the initial position assumed nill then x(0) =0 finally the distance d is x(t) =d= vt...

i would like to know all the details about the band structure in a semiconductor and in particular what we call : yours sincerly guedman

90make the variable change assume X = (E-[E][/C]/kT)

only the tranverse solution is a solution in the VACUUM but in material the two kinds can exist
