Description

Performance Analysis and Transport Physics Modeling of III-V FETs Using Cellular Monte Carlo Simulation Performance Analysis and Transport Physics Modeling of III-V FETs Using Cellular Monte Carlo Simulation Monte Carlo simulation is a powerful modeling tool to analyze the device transport in different transport regimes: from ballistic to dissipative. III-V devices have high carrier mobilities and are believed to operate close to ballistic regime. It is seen in experiments that performance of III-V devices is affected by high voltage operation, high carrier densities in the channel, and by device design such as, for example, using dielectric layers to minimize gate leakage for device scaling. In III-V devices due to high mobility, the transient effects, such as velocity overshoot effects, are more pronounced in scaled devices than in lower mobility Si devices. Full bandstructure effects on transport, such as carrier transfer between the valleys, the operating principle of electrontransferred diodes are essential to include in the simulation of III-V devices. Stress engineering which has been successfully used for Si device improvement needs to be explored for III-V devices. Monte-Carlo method is ideally suited to study the physics of scaled devices the regime of the transition from the ballistic transport to dissipative, transient effects, and full bandstructure effects. The work performed by the ASU group (S. M. Goodnick and M. Saraniti) will focus on two primary efforts for the three year duration of the project: implementation of new functionality in the existing Cellular Monte Carlo (CMC) code (here referred to as the code) as described in Section 3, and its maintenance and transfer to Intel (see Section 4 and 5). Simulations of scaled devices of interest to Intel will be performed as well in collaboration with the modeling and simulation group at Intel for the duration of the project. The code will be distributed to a limited group of Intel researchers under the code transfer agreement discussed below.
