I just took up my first course of quantum mechanics and i am having some serious problems solving quantum well problems.the thing is that after i take out the energy states of the well(adsbygoogle = window.adsbygoogle || []).push({});

and try to find K1 and K2 from it, the values i get are very very large.i think i am making a msitake with units somewhere.here r the units that i am taking.can someone plz point out where im making a mistake.

K1=sqrt(2*m*E/h^2)

K2=sqrt(2*m*(V-E)/h^2)

E=energy(i am converting ev to Joules)

V=well depth(i am again converting ev to J)

m=e mass(9.1e-31)

h=1.054e-34 J.s

all lengths in meters

So if for example E=.245ev ,V=.36ev,what values of K1 and K2 should i be getting.

Thanx
