Abstract

The combined effect of temperature and conduction band non-parabolicity on the ground and low-lying excited
states of an electron in a gallium arsenide spherical quantum dot (SQD) have been studied. The results are
presented for the SQD with square well confinement corresponding to different values of x. Our result shows the:
(i) The confined energies decreases as the dot size increases, (ii) it increases with increase within temperature,
and (iii) further it decreases due to the application of conduction band non-parabolicity. All the calculations have
been carried out with finite models, and the results are compared with existing literature.
