Quantum well Definition and 58 Threads

Homework Statement (a) Determine the reflectivity spectrum R(E) of a free particle of mass m reflected from an infinite jump V(x), where V(x)=0 if x\leq0, V(x)=-\infty if x>0 The other similar problem is: (b) Determine the energy levels of a particle of mass m confined to an infinite...

When the depth of a quantum well increases, the first level increases or decreases its energy with respect of the bottom of the quantum well?

Does anyone knows how to solve the following eigenvalue equation using matlab? so as to obtain the energy levels in a quantum well structure.. or does anyone has the codes or knows where to find the codes to do so? Eigenvalue equation: tan(sq_root(2mE/hbar^2)*(d/2)) = sq_root((V-E)/E) for...

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 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...

Sir: I need the knowledge of the quantum well, who can help me?

suppose we have a single eigen-state finite potential well like following: V(x)= V, x<-a and x>a; 0, -a<=x<=a; say only one eigen-state within this well S1(x) when all of sudden this potetial well broden by size of 2 V(x)= V, x<-2a and...
