| 英文摘要 | The subbands of the ground state e(c1), the first excited state e(c2) and heavy hole state e(hh1) are calculated by solving the eigenvalues of effective-mass hamiltonian h(0) which is derived from eight-band k . p theory and the calculations are performed at k(x) = k, = k = 0 for the three-dimensional array of ingaas/gaas quantum dots (qds). with indium content in ingaas qds gradually increasing from 30% to 100%,the intersubband transition wavelength of e(c2) to e(c1), blue-shifts from 18.50 to 11.87 mu m,while the transition wavelength of e(c1), to e(hh1), red-shifts from 1. 04 to 1. 73 mu m. with the sizes of ir(0.5) ga(0.5) as and inas qds increasing from 1.0 to 5.0 nm, the intersubband transition from e(c1), to e(c2) transforms from bound-state-to-continuum-state to bound-state-to-bound-state, and the corresponding intersubband transition wavelengths red-shift from 8.12 pm (5.90 pm) to 53.47 mu m (31.87 pm), respectively, and the transition wavelengths of e(c1) to e(hh1) red-shift from 1. 13 mu m (1.60 mu m) to 1.27 mu m (2.01 mu m), respectively. |
