The 1D simplification allows using the wave operator like a function of the z coordinate only: (47) (r,z) = (z)eikr, where k=(kx,ky) is the wave vector in the (x,y) plane. So the carrier are quantized in the z direction and are free to move in the r=(x,y) plane, with a continuous energy component. After phase transformation and imposing the constraint of vanishing for the first derivative of the wave function, the envelope 1D time-independent reduced equation (46) is: (48) z W E z 2 m where is reduced Planck constant, mzz is the effective masses in mo units, W is potential energy, (z) is the 1D envelope wave functions and Ez is the eingenvalue energy.
