Simulation Tools for Solid State Devices and MEMS

[Jay_]

I have worked with softwares that help me simulate circuits (Hpice, Proteus, MultiSim), but is there a software that helps me simulate devices right from the level of the atom?

For instance, I should be able to create a pattern of boron with silicon atoms, and then be able to replicate it 1 billion times. And then take a small (defined) piece of it for my p-type. Similarly with N-type. Or I should be able to type in my doping concentrations and then simulate.

So that way I can create SSDs (not just BJTs, MOSFETs, but describe any material I want) and see how they work on different voltages, biases and connections, etc. I think there should be a software that presently exists for designing and testing from the level of the atom, though I don't know its name.

The recent conference of ITRS spoke of modeling and simulation, though I didn't catch what software they used. I read one TCAD which is used but Technology Computer Aided Software is too general a term. So, which simulation tool or software goes down to the atom level, for modelling and simulating SSDs and MEMS?

Most of the software used for atom-level simulations is used in research institutions and universities. Examples include Quantum Espresso, CASTEP, VASP, and NWChem. Some of these are open source packages, so they may be available to individuals for free or for a nominal fee. Additionally, some commercial software packages, such as NanoHUB, offer atom-level simulation tools that can be used by professionals.
