约翰·巴丁(John Bardeen, 1908~1991)是迄今为止唯一的一位在同一领域中两次获得诺贝尔物理学奖的科学家。1956 年, 巴丁与W. 布拉顿(Brattain)以及W. 肖克利(Shockley)由于在半导体研究方面的突出贡献, 并且发现了晶体管效应而获得诺贝尔物理学奖。第二次获奖是由于超导微观理论(BCS 理论)的建立, 巴丁与L. N. 库珀(Cooper)和J. R. 施里弗(Schrieffer)一起分享了1972 年的诺贝尔物理学奖。 相似文献

著名物理学家巴丁教授来我国讲学 总被引:1,自引:0,他引:1
美国著名物理学家巴丁(J·Bardeen)教授应中华人民共和国教育部和北京大学校长周培源的邀请于1980年5月来我国讲学.巴丁教授曾两次获得诺贝尔桨金物理奖.第一次是在1956年与勃拉丁(Brattain)和肖克莱(Schockley)合得的,得奖是由于其半导体理论导致晶体管的发明.第二次是在1972年由于他和年轻的物理学家库珀(Cooper)、施里弗(Schrieffer)一起创立了超导电性的微观理论(现通称为BCS理论). 巴丁教授在北京大学讲学期间,作了有关“超导问题的发展与近况”、“超导计算机发展近况”、“量子阶异质结激光器”等方面内容的报告共7次.对近年来在… 相似文献

This account of the history of the Bardeen–Cooper–Schrieffer theory of superconductivity has its roots in an assignment that Quin Luttinger designed for me in 1963 when I was his graduate student. It improves on my student work by tracing the story from historical source materials as well as published papers, thus reflecting the contingencies and human elements that shape all research in physics. I also made an attempt to portray general features of how John Bardeen approached solving problems in physics. 相似文献

The investigation of electron transport processes in nano-scale architectures plays a crucial role in the development of surface chemistry and nano-technology. Experimentally, an important driving force within this research area has been the concurrent refinements of scanning tunneling microscopy (STM) techniques. The theoretical treatment of the STM operation has traditionally been based on the Bardeen and Tersoff–Hamann methods which take as input the single-particle wave functions and eigenvalues obtained from finite cluster or slabs models of the surface-tip interface. Here, we present a novel STM simulation scheme based on non-equilibrium Green’s functions (NEGF) and Wannier functions which is both accurate and very efficient. The main novelty of the scheme compared to the Bardeen and Tersoff–Hamann approaches is that the coupling to the infinite (macroscopic) electrodes is taken into account. As an illustrating example we apply the NEGF-STM method to the Si(001)-(2×1):H surface with sub-surface P doping and discuss the results in comparison to the Bardeen and Tersoff–Hamann methods. 相似文献
