MULHACEN, enhanced multi-subband Monte Carlo simulator for nonplanar FETs Donetti, Luca Medina Bailón, Cristina Padilla, José Luis Sampedro Matarín, Carlos Gámiz Pérez, Francisco Jesús Monte Carlo Multi-subband 2D Schrödinger In this work, we present Mulhacen, a 3D multi-subband simulator developed for the accurate study of nonplanar devices which are at the core of present and future technology nodes. It allows to consider electrons in different conduction band valleys and, among its main features, we can highlight the accurate evaluation of quantum effects in the plane transverse to transport through the solution of the 2D Schrödinger equation in several device cross sections, as well as Monte Carlo description of transport. The simulator is based on a finite elements discretization, which allows an accurate description of realistic device geometries. 2025-09-25T11:58:12Z 2025-09-25T11:58:12Z 2025-12 journal article Donetti, L., Medina-Bailon, C., Padilla, J.
