Low Field Mobility

The strain-dependence of electron transport in bulk Si and deep-submicron MOSFETs is investigated by full-band Monte Carlo simulation. On the bulk level, the drift velocity at medium field strengths is still enhanced above Ge-contents of 20% in the substrate, where the low-field mobility is already saturated, while the saturation velocity remains unchanged under strain. In an n-MOSFET with a metallurgical channel length of 50nm, the saturation drain current is enhanced by up to 11%, but this maximum improvement is essentially already achieved at a Ge-content of 20% emphasizing the role of the low-field mobility as a key indicator of device performance in the deep-submicron regime.

ABSTRACTWe study electron transport in the alloys of aluminum nitride and gallium nitride and alloys of indium nitride and gallium nitride. In particular, employing Monte Carlo simulations we determine the velocity-field characteristics associated with these alloys for various alloy compositions. We also determine the dependence of the low-field mobility on the alloy composition. We find that while the low-field mobility is a strong function of the alloy composition, the peak and saturation drift velocities exhibit a more mild dependence. Transient electron transport is also considered. We find that the velocity overshoot characteristic is a strong function of the alloy composition. The device implications of these results are discussed.
