Optical Physics of Quantum Wells - Stanford EE
ee.stanford.eduThe simplest "k.p" band theory says that the electron effective mass, me, and the light hole effective mass, mlh, are approximately equal and proportional to the band gap energy. For GaAs, which has a band gap energy of ~ 1.5 eV, the actual values are me ~ 0.069 mo and mlh ~ 0.09 mo, where mo is the free electron mass.

Band Structures and the Meaning of the Wave Vector k
www.mrl.ucsb.eduBand Structures and the Meaning of the Wave Vector k Leo K. Lamontagne 1 Introduction Band structures are a representation of the allowed electronic energy levels of solid materials and are used to better inform their electrical properties. A band structure is a 2D representation of the energies of the crystal orbitals in a crystalline material.
