摘要：

The spin-splitting factor g* of the electrons at the very bottom of the conduction band in strained GaxIn1-xAs/InP type-I quantum wells is reported. Experimental proof of quantum confinement-dependent anisotropy of g* is given. Changing the alloy composition at fixed quantization, equivalent to introducing compressive and tensile strain, changes g*. The values of g* perpendicular to the quantum-well plane can be explained in a model calculation. Apparently however, no quantitative theory on which to base the calculation of the anisotropic spin splitting is at present available.
