High-field charge transport and noise in p-Si from first principles

Kavli Affiliate: Austin Minnich | First 5 Authors: David Catherall, Austin Minnich, , , | Summary: The parameter-free computation of charge transport properties of semiconductors is now routine owing to advances in the ab-initio description of the electron-phonon interaction. Many studies focus on the low-field regime in which the carrier temperature equals the lattice temperature […]

A method to computationally screen for tunable properties of crystalline alloys

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Matthew K. Horton, Kristin A. Persson, , | Summary: Conventionally, high-throughput computational materials searches start from an input set of bulk compounds extracted from material databases, and this set is screened for candidate materials for specific applications. In contrast, many functional materials, and especially […]

How Material Heterogeneity Creates Rough Fractures

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Will Steinhardt, Shmuel M. Rubinstein, , , | Summary: Fractures are a critical process in how materials wear, weaken, and fail whose unpredictable behavior can have dire consequences. While the behavior of smooth cracks in ideal materials is well understood, it is assumed that for real, […]
