Marlene Morrison,Sheila Gallowayort (the charge carriers experience no, or only few, collisions within the active region of the device); here we point out the difference between quantum ballistic transport, such as underlies resistance quantization in quantum point contacts (van Wees ., 1988; Wharam ., 1988) and ballistic peaks ob

It was shown (Berggren ., 1986), that the additional magnetic field increases the ID subband spacing, so that lD-subbands are shifted above the Fermi energy if the magnetic field is increased. Consequently, these subbands are depopulated, resu

TAG

Non-Equilibrium Carrier Transport in Small Structures, which makes it difficult to establish a proper guideline for designing small geometry devices. Especially, detailed understanding of high-field effects in future deep submicron devices strongly requires a precise knowledge on non-equilibrium carrier transport.

Unfortunately, electronic transport that reveals quantum size effects in these systems only occurs for low temperatures (<1 .) and voltages near equilibrium (typically of the mV level) (Williamson .., 1990).
