Abstract :
The authors consider the strain dependence of FET performance in the nonlinear operation regime by full-band Monte Carlo (FBMC) simulation and investigate how this behaviour is related to the corresponding transport properties in strained bulk Si. Enhanced drain currents of up to 20% were found in n-MOSFETs under strain which could be mainly related to higher low-field mobilities, but enhanced bulk velocities at medium fields appear to have a significant influence at the highest drain voltages.
