We investigate the characteristics of low-frequency oscillations in semi-insulating GaAs as a function of bias voltage. We find a change in character from simple periodic to irregular, chaotic behavior. A theoretical model is outlined which emphasizes the role of diffusion. The oscillations in SI GaAs are compared to similar phenomena in other semiconductors. A universality of behavior among the various materials is observed and explained.
