    • A semiconductor device (10) for emitting, upon receiving a light energy, a highly spin-polarized electron beam, including a first compound semiconductor layer (14) formed of gallium arsenide phosphide, GaAs 1-x P x , and having a first lattice constant; a second compound semiconductor layer (16) grown with gallium arsenide, GaAs, on the first compound semiconductor layer, and having a second lattice constant different from the first lattice constant; and a fraction, x, of the gallium arsenide phosphide GaAs 1-x P x and a thickness, t, of the second compound semiconductor layer defining a magnitude of mismatch between the first and second lattice constants, such that the magnitude of mismatch provides a residual strain, ε R , of not less than 2.0 x 10⁻³ in the second layer. The fraction x of the gallium arsenide phosphide GaAs 1-x P x and the thickness t of the second compound semiconductor layer may define the magnitude of mismatch between the first and second lattice constants, such that the magnitude of mismatch provides an energy splitting between a heavy and a light hole band in the second layer so that the energy splitting is greater than a thermal noise energy in the second layer.
    • 一种用于在接收到光能时发射包括由砷化镓磷化物GaAs1-xPx形成的第一晶格常数的第一化合物半导体层(14)的高度自旋极化的电子束的半导体器件(10) 在所述第一化合物半导体层上生长有砷化镓(GaAs)的第二化合物半导体层(16),并且具有与所述第一晶格常数不同的第二晶格常数; 和砷化镓磷化物GaAs1-xPx的分数x和第二化合物半导体层的厚度t定义第一和第二晶格常数之间的失配量,使得失配量提供残余应变, εR在第二层中不小于2.0×10 -3 <3。 砷化镓磷化物GaAs1-xPx的分数x和第二化合物半导体层的厚度t可以限定第一和第二晶格常数之间的失配的大小,使得失配的大小提供了重的和 在第二层中的光空穴带,使得能量分裂大于第二层中的热噪声能量。
