Patent JP-H02184083-A (JP)
Title: Semiconductor device
Inventor: TAGAMI TOMONORI
IPC: H01L31/107
Filed: 1989-01-11
Abstract: PURPOSE:To realize the spatial isolation of electrons and holes in the same structure and obtain an element having a new function by determing the thickness of semiconductors of a quantum well layer and a clad layer and of the quantum well layer so that the quantization energy which arises in the quantum well layer is higher than the conductance band of the clad layer, and that of a hole is lower than the valence electron band of the clad layer. CONSTITUTION:On a GaAs substrate 1 are in turn accumulated the following layers by a molecule beam epitaxy method to form a multiquantum well structure 108: an n-type AlxGa1-xAs (x=0.1) clad layer 101 (thickness: 1000Angstrom , Si density: 1X10<18>/cm<3>), an undoped AlyGa1-yAs (y=0.5) barrier layer 102 (thickness: 50Angstrom ), a GaAs quantum well layer 103 (thickness: 40Angstrom ), a barrier layer 104 having the same thickness and material quality as that of the barrier layer 102, and a clad layer 105 having the same thickness and material quality as that of the clad layer 101. As a result, the electron energy is higher in the GaAs quantum well than in the GaAs layer. On the valence electron band side, the hole energy is lower in the GaAs quantum well by the effect that the effective mass of a heavy hole is larger. Thus, if an electron-hole pair occurs in this structure, electrons collect in the AlGaAs clad layer because of tunneling and holes collect in the GaAs quantum well layer, thereby electrons being spatially isolated from holes.
