Scaling of pHEMTs to decanano dimensions [PDF]
7th International Workshop on Computational Electronics. Book of Abstracts. IWCE (Cat. No.00EX427), 2001 The effect of scaling into deep decanano dimensions on the performance of pseudomorphic high electron mobility transistors (pHEMTs) is extensively studied using Monte Carlo simulations. The scaling of devices with gate lengths of 120, 70, 50 and 30nm is performed in both lateral and vertical directions.
