| Abstract: | Using the Born formula,an approximate expression of the dielectric constant with pressure or strain is given.The exciton binding energies and the transition energies of ZnCdSe/ZnSe quantum wells under hydrostatic pressure are calculated using the variation method with consideration of the influence of pressure or strain on the dielectirc constant,effective masses,lattice constants and other physical quantities.The calculation results are discussed and compared with other author’s experimental and theoretical work. |
