Abstract

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.

用于非平面场效应管的增强型多子带蒙特卡罗模拟器

在这项工作中，我们介绍了mulhazen，一个3D多子带模拟器，用于精确研究非平面器件，这些器件是当前和未来技术节点的核心。它允许考虑不同导带谷中的电子，并且在其主要特征中，我们可以突出通过在几个设备横截面中求解二维Schrödinger方程来准确评估横向平面上的量子效应，以及对传输的蒙特卡罗描述。该模拟器基于有限元离散化，可以准确描述实际的器件几何形状。
