How far does the wave function extend

Reference no: EM131349383

A monolayer of In As between GaAs can be modelled very roughly as a potential well for electrons of depth 1 eV and width 0.3 nm, with effective masses 0.025 inside and 0.067 outside. Calculate its bound state(s) for k = 0. How far does the wave function extend? Is a δ-function a good approximation to the potential?
