Hi,
I've worked out that for the particle-in-a-box model (square well) the energy E
E = 3h^2/8mL^2
where m is the effective mass of the electron.
The next question asks
Hence derive an expression for the variation of the effective energy gap in the quantum dot as a function of its size for a semiconductor material that has a bulk energy gap Eg and electron and hole effective masses of m and m_h.
I haven't studied semiconductor physics in detail so I don't know how to proceed. Thanks for your input.
