Calculation shown that the refraction index of Ge_0.6Si_0.4/Sistrained-layer superlattice n≈3.64, when L_w=9 nm and L_b=24 nm. Analgorithm of numerical iteration for effective refraction index isemployed to obtain di...
The electronic structures of wurtzite compounds GaN,AIN and strained-layer super-lattice(SLS)(Ga_(2)N_(2))_(1)(Al_(2)N_(2))_(1)(001) constituted by straining GaN-layer to match the lattice constant of AIN according to...
Ⅰ. INTRODUCTION The coulomb interaction between electron and hole has been enhanced in the quasi-two-dimensional (2D)electronic system in quantum well or superlattice structure, especially by the potential confinemen...
I. INTRODUCTION The wide gap semiconductor superlattioes and quantum wells fabricated by ZnS, ZnSe and ZnTe are expected to be greatly useful in the optoelectronics area in the visible region. 600-700 nm wavelength op...
