Abstract
It is shown that free carriers in a solid may be treated as a moving dispersive medium which causes a Fresnel drag effect. We have succeeded in detecting the resulting small change in refractive index, using an InAs specimen placed inside a ring laser operating at 3⋅39 μm. Excellent agreement is obtained between experiment and theory. This is believed to be the first observation of a relativistic effect produced by carriers moving in a solid.
