摘要：

In this paper, we have studied theoretically the effects of the, temperature, hydrostatic pressure and the composition on the intersubband transition energies. We have used a mathematical method, which based on a combination of coordinate transformation and the finite difference method. We have controlled the size and shape of core shell quantum dot CSQD by varying the parameters introduced in the function of coordinate transformation. We have studied the influence of hydrostatic pressure and temperature on the optical properties.
