THEORY & MODELLING of CHARGE TRANSPORT in SEMICONDUCTING NANOWIRES-BASED DEVICES A postdoctoral position (2 years) is opened at CEA/DRFMC (Grenoble, France) starting from January 2008 to work on the theory and simulation of charge transport in semiconducting nanowires (SC-NWs) based materials and devices (field effect transistors). Chemically grown semiconducting nanowires are showing unprecedented structural quality which make them ideal systems to explore transport physics in low dimensionality, as well as to engineer novel nano-devices and architectures for nanoelectronics and optoelectronics applications. In this context, theoretical modeling and computational simulations are needed to deepen the understanding of the fundamental transport mechanisms in these systems. The theory group of the CEA is presently developing several computational approaches to tackle the problem of charge transport in realistic models of SC-NWs, including device (field effect transistors) simulation. Sophisticated tight-binding order N methods have been developed to investigate charge transport in different frameworks (Kubo, Landauer-Büttiker, and Non Equilibrium Green's Function formalism (NEGF), self-consistent Poisson Schrödinger Solvers). Ab-initio approaches are also used for detailed understanding of atomic-scale features (doping, defects, interfaces,.…). These methodologies enable to address the intrinsic (quantum)-transport properties of ideal and doped/disordered nanowires, as well as SC-NWs-based device characteristics. This work will be performed within the context of the European Integrated Project "NODE" (Nanowire-based One-Dimensional Electronics). The candidate will be in charge to investigate the transport properties of various semiconducting nanowire systems, in conjunction with transport experiments performed within the consortium. This will include exploration of quantum transport phenomena in low dimensional systems, as well as device oriented issues. The candidate should have demonstrated some experience in state of the art semi-empirical or/and ab-initio methods, and preference will be given to people already familiar with transport physics, and/or electronic structure of semiconducting materials in confined geometries. The candidate should send her/his CV to Yann-Michel Niquet (yniquet@cea.fr) and Stephan Roche (stephan.roche@cea.fr), with a list of publications, and contact details of two persons for references. The deadline for submitting applications is October 1, 2007 Additional informations about the Theory group: http://www-drfmc.cea.fr/SP2M/L_Sim/QUI/YMNiquet http://www-drfmc.cea.fr/Pisp/22/stephan.roche.html More about Grenoble and its surroundings : http://www.isere-tourisme.com/pages/index/id/1356
