We address the formation of optical surface waves at the very edge of semiconductor materials illuminated by modulated light beams that generate thermal waves rapidly fading in the bulk material. We find families of thresholdless surface waves existing owing to the combined action of thermally-induced refractive index modulations and instantaneous Kerr-type nonlinearity.
