Course on Beyond CMOS Computing
06 Jun 2013 | Teaching Materials | Contributor(s): Dmitri Nikonov
Complementary metal-oxide-semiconductor (CMOS) field effect transistors (FET) underpinned the development of electronics and information technology for the last 30 years. In an amazing saga of development, the semiconductor industry (with a leading role of Intel) has shrunk the size of these transistors from 1000nm to 22nm. As this size approaches atomic limits, the research community is under pressure to find devices which complement CMOS and enable further improvement of performance of …
MOSCNT: code for carbon nanotube transistor simulation
14 Nov 2006 | Downloads | Contributor(s): Siyu Koswatta, Jing Guo, Dmitri Nikonov
Ballistic transport in carbon nanotube metal-oxide-semiconductor field-effect transistors (CNT-MOSFETs) is simulated using the Non-equilibrium Green’s function formalism. A cylindrical transistor geometry with wrapped-around gate and doped source/drain regions are assumed. It should be noted that this code does NOT treat Schottky-barrier CNTFETs.
MATLAB DOs and DON'Ts
14 May 2006 | Online Presentations | Contributor(s): Dmitri Nikonov
Matlab is widely used for simulations but is believed to be unsuitable for complex projects and to produce slow-running software tools. The presentation argues that blind copying of methods typical of C and Fortran is responsible for such inefficiencies; the presentation teaches avoidance of these mistakes and improvement of the run time and usability of codes by using unique Matlab methods. Tools for optimizing the code and good software practices are also discussed.
Modeling of Nanoscale Devices
19 Oct 2006 | Papers | Contributor(s): M. P. Anantram, Mark Lundstrom, Dmitri Nikonov
We aim to provide engineers with an introduction
to the nonequilibriumGreen’s function (NEGF) approach, which is a powerful conceptual tool and a practical analysismethod to treat nanoscale electronic devices with quantum mechanical
and atomistic effects. We first review the basis for the traditional, semiclassical description of carriers that has served device engineers for more than 50 years. We then describe why this traditional approach loses validity at the nanoscale. Next, we describe ...
recursive algorithm for NEGF in Matlab
