摘要
Evidence of one-dimensional subband formation is found at low temperature in trigate silicon-on-insulator MOSFETs, resulting in oscillations of the ID(VG) characteristics. These oscillations correspond to the filling of energy subbands by electrons as the gate voltage is increased. High mobility, reaching 1200 cm(2)/Vs, is measured in the subbands at T = 4.4 K. Subband mobility decreases as temperature is increased. Conduciion in subbands disappears for temperatures higher than 100 K or for drain voltage values that are significantly larger than kT/q.
