Quantum Ballistic Transport

  • Y. B. Levinson
Part of the NATO ASI Series book series (NSSB, volume 264)


Quantum ballistic transport occurs in devices microfabri-cated by lateral patterning of the high-mobility two-dimensional electron gas (2DEG) in a GaAs/AlG-aAs heterojunct i on, A quantum ballistic device (QBD) is a channel1,2 (constriction) or a net of channe3,4,5 with length L shorter than elastic scattering mean free path ℓ (about 10 μm) and width d of the order of Permi wavelegth λF (about 50 nm). The narrow channels are connected with wide contact pads (reservoirs), where the current enters the device and the applied voltage is measured.
