摘要：
Ballistic transport and low-frequency noise are studied for two-dimensional electrons of very high electron mobility. Using macroscopic-scale devices, we reveal two major properties of ballistic transport : long-distance ballistic transport of electrons and size-independent resistance. These behaviors are well reproduced by the Landauer-Buttiker formula in the classical limit. We observe critical noise generation for a large injection current in a wide channel device. This arises from nonequilibrium electron heating under high electric field.
