Abstract:
Thin 111 wafers of GaAs, InAs, GaSb and InSb, 5 to 25 microns thick, were found to bend spontaneously, the A surface being convex. Such bending is consistent with the elastic strain energy associated with the distortion of the bonding configuration on the A surfaces of the III-V compounds. Exposure of the thin wafers to NH3 resulted in an increase in the radius of curvature whereas exposure to H2S resulted in a decrease in the radius of curvature. These effects are believed to result from preferential adsorption. Author
