Description
Detector technologies based on solid-state devices are of growing interest in both academic and industrial research. Understanding their performance limitations and finding effective mitigation strategies are therefore high priorities. Among the common tools to study device performance are Monte-Carlo simulations. In high-energy particle physics, the Geant4 toolkit is broadly used to simulate the response to various types of radiation hits. Many research groups are now pursuing detailed simulations of radiation effects on solid-state devices for a variety of applications such as dark matter experiments and quantum computing with superconducting qubits. The Geant4 Condensed Matter Physics (G4CMP) package provides an extension of solid-state physics to the particle physics simulation suite in Geant4. At its core, G4CMP introduces quasiparticles such as phonons and charge carriers, which are freed in particle interactions in cryogenic crystals, and governs their propagation in the substrate and absorption in thin-film sensors according to its implemented physics models.
In addition to presenting the physics and features supported by G4CMP and recent developments, this talk outlines example applications from the dark matter and quantum information science communities.
