Abstract: A novel approach is proposed, termed Partial-Coupled Mode Space (PCMS), for simulation of quantum transport in nanoscale devices. The PCMS integrates advantage of Coupled Mode Space (CMS) in accuracy and Uncoupled Mode Space (UMS) in reduction of computational burden. Partial coupling between the modes of the nanoscale device is achieved by coupling the odd-modes and even-modes separately. N-type FinFETs were simulated by the proposed approach and compared with the fully CMS accuracy and simulation time. The simulation was carried out on set of devices that satisfy the requirements of the International Technology Roadmap for Semiconductors (ITRS). The simulations show that our PCMS saves more than 65 % of the computational time with error less than 0.1 % and 0.01 % in the device charge and terminal current respectively compared to the CMS.
