A Monte Carlo study ,of Electron Transport in Strained Si/SiGe Heterostructures


Electron transport in pseudomorphically-grown silicon on relaxed (001) Si1-xGex is investigated using a Monte Carlo (MC) simulation tool. The study includes both electron transport in bulk materials and in nMOS structures. The bulk MC simulator is based on a multiband analytical model, “fitted bands”, representing the features of a realistic energy bandstructure. The investigation includes the study of low- and high-field electron transport characteristics at 77 K and 300 K. Single particle MC simulations are performed for a strained silicon nMOS structure at room temperature. Both calculations show saturation of mobility enhancement in strained silicon beyond germanium mole fraction of 0.2.
