29. Effect of strain on the E – k dispersion of GaAs in 1-D using the K.P method.BY Arthur I. Ejere, Aigbekaen E. Eddy and Okocha O. Godstime Transactions of NAMP Volume 5,(September and November, 2017), pp 223 – 230
Sale price: $5.00


The Energy – wave vector (E- k) dispersion of Gallium Arsenide (GaAs) and the effect of strain on the dispersion is  investigated.                                                                                                                                                                                                       
The K.P method is used instead of other methods like; tight binding and pseudopotential methods  because this method has an advantage of giving realistic band structure close to the Г point without being too demanding on computer resource.
The 1 – D, E – k dispersion plots shows significant effect of strain even in the neighborhood of the Г point.
