postdoc: ab initio simulation of million atom transistors

Joint postdoctoral positions (1-2) of Institue of Semiconductors Chinese Academy of Sciences (IOSCAS, Beijing,http://www.semi.ac.cn ) and Material Science Division of Lawrence Berkeley National Laboratory (LBNL, Berkeley CA, http://www.lbl.gov ) are now available. The work site is based in Beijing, while regular visit to LBNL is available (half of the duration). The co-advisers include Prof. Shu-Shen Li (director) of IOSCAS, and Prof. Lin-Wang Wang in LBNL (http://cmsn.lbl.gov/index.php?topic=people ).

The successful candidates are expected to carry out researches on fully ab initio simulations of industrial level million atom field-effect transistors (FETs) including the following features:

1. Physics of surfaces and interfaces in industrial level semiconductor devices (most likely FETs): Understanding metal-semiconductor contact properties and carrier dynamics at dielectric (oxide)-semiconductor interfaces by pushing large scale ab initio simulations up to 10,000 atoms.
2. Large scale ab initio quantum transport calculation methodology development based on plane waves and linear scaling techniques such as linear scaling three-dimensional fragment method and folded spectrum method. This effort is to scale the ab initio quantum transport calculation up to 100,000 atoms.
3. Combine the above two to implement fully ab initio simulations of the whole industrial level semiconductor device containing all components (metal contact, dielectric interface, source-channel-drain, atomic dopant if necessary).

The candidates are required to have a PhD degree in condensed matter physics or material science. Experience on electronic structure theories (DFT and beyond), computational simulations of solids, nanostructures and nanodevices is preferred.

The gross salary will be $3,500 (USD) per month. A bonus based on annual publications will be available. IOSCAS provides a two bedroom apartment in Beijing. The positions are available for two years at the initial instance, with the possibility of extension based on mutual agreement.

The start date is immediate. Please send your CV, research statement (1 page) and contact information of 2 academic references, directly to Prof. Xiang-Wei Jiang by email (xwjiang@semi.ac.cn ). The search is open until the positions are filled. Informal inquiry can be made by contacting Prof. Jiang.
