SCIENTIFIC CONTENT

The last few years have witnessed rapid developments in semiconductor mathematical research including modeling, analysis and numerical simulations of semiconductor device equations, ranging from the Schroedinger equation for the evolution of the electron wave function to the drift-diffusion system for the evolution of the 'electron gas' which is close to a Maxwellian equilibrium. Like semiconductor devices, many proteins and biological systems are also devices in exactly the engineering sense of the word. These devices have a definite function described by an approximate device equation that is valid ONLY when the device is working as designed. Devices have complex internal structure that allows them to have a reasonably robust and simple equation and much of biological research is really an inverse problem to determine the device equation.

The diversity of physical architectures for semiconductor devices and biological ionic channels as well as the mathematical models they are based on has proven to be a fruitful ground for interaction of researchers from different disciplines in physics, biology, engineering, mathematics and scientific computation.

We plan to revisit existing intersections and to explore future directions in modeling, analysis and numerics of classical and quantum transport in semiconductor devices, and classical transport in biological ionic channels, and related topics.

WORKSHOP OBJECTIVES

The last two decades have seen an enormous amount of research activities in both mathematical analysis and numerical simulations of the semiconductor device equations as well as the ion transport equations for biological channels. We can foresee even more activities in this area given the potential industrial applications of semiconductor device and biological channel modeling.

This workshop will bring together experts representing a variety of different approaches to semiconductor models as well as biological systems to report their current research results in order to foster future collaborations and strengthen existing ones between mathematicians and semiconductor/biological channel researchers.

This week-long workshop will consist of expository lectures by leaders in different disciplines, regular research presentations and panel discussions on future directions. Interactions between people from different communities will be an important component of the workshop.


FOCAL POINTS

  • Classical & quantum transport in semiconductor devices
  • Semi-classical device modeling: hydrodynamic and kinetic models
