G4CMP使用Geant 4工具包模拟低温半导体晶体中的声子和电荷输运。传输代码能够模拟声学声子以及电子和空穴电荷载流子的传播。包括各向异性声子传播，斜电荷载流子传播，声子发射加速电荷载流子的过程。模拟再现的理论预测和实验观察，如声子焦散线，热脉冲传播时间，和平均载流子漂移速度。除了介绍G4CMP支持的物理和功能外，本报告还概述了暗物质和量子信息科学社区的示例应用。这些社区正在应用G4CMP来建模和设计设备，其中声子和电荷载流子传输的能量与放置在硅和锗衬底上的超导仪器和电路的性能密切相关。G4CMP包可以从GitHub下载：github.com/kelseymh/G4CMP。
G4CMP simulates phonon and charge transport in cryogenic semiconductor crystals using theGeant4toolkit. The transport code is capable of simulating the propagation of acoustic phonons as well as electron and hole charge carriers. Processes for anisotropic phonon propagation, oblique charge-carrier propagation, and phonon emission by accelerated charge carriers are included. The simulation reproduces theoretical predictions and experimental observations such as phonon caustics, heat-pulse propagation times, and mean charge-carrier drift velocities. In addition to presenting the physics and features supported by G4CMP, this report outlines example applications from the dark matter and quantum information science communities. These communities are applying G4CMP to model and design devices for which the energy transported by phonons and charge carriers is germane to the performance of superconducting instruments and circuits placed on silicon and germanium substrates.
