U.S.-China Cooperative Research: "Theory of High Field Transient Processess"

城市学院的Joseph Birman和中国科学院理论物理研究所的苏兆斌合作，致力于更好地从理论上理解微器件的非平衡输运理论。这是建立在Birman和Su之间早期合作的基础上的。近年来，新型半导体材料和新型异质结器件已经生产出来，具有新颖的电子特性。由于分子束外延和金属有机化学气相沉积等复杂技术的发展，这使得新型工程和特殊结构的制造成为可能。谐振隧道晶体管是最有前途的电子功能器件之一，它允许以大大降低复杂性的方式实现大量电路。对这些晶体管特性的研究将提高对它们在开发新器件，甚至是开发新的计算机体系结构方面的潜力的理解。

This collaboration between Joseph Birman, City College, and Su Zhaobin, Institute of Theoretical Physics, Chinese Academy of Sciences, focuses on developing a better theoretical understanding of the non-equilibrium transport theory of microdevices. This builds on earlier collaboration between Birman and Su. New classes of semiconductor materials, and new types of heterjunction devices, with novel electronic properties have been produced in recent years. This has been made possible by development of sophisticated techniques such as molecular beam epitaxy and metallorganic chemical vapor deposition which allow new types of engineering, and fabrication of special structures. Resonant tunneling transistors are emerging as some of the most promising electron functional devices, allowing implementation of a large class of circuits with greatly reduced complexity. Investigation of the properties of these transistors will improve understanding of their potential in development of new devices, and even in development of new computer architectures.
