Abstract
G4CMP simulates phonon and charge transport in cryogenic semiconductor crystals using the GEANT4 toolkit. 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. The G4CMP package is available to download from GitHub: github.com/kelseymh/G4CMP.

The original development of G4CMP took place more than a decade ago [2]. Many have contributed to the package since that time. Our intention with this article was to bring all contributors together with several “user groups” for an updated presentation of the code and breadth of potential application. Thus, this work was truly a multi-collaboration endeavor. The authors thank each of their respective sponsoring agencies for making possible the development and use of the G4CMP software package.
