Overview

This investigation reveals how substitutional platinum enhances nonradiative recombination in silicon devices, suggesting potential performance improvements.

Key Points

To explore the nonradiative recombination mechanism of substitutional platinum in silicon using advanced calculations.
First-principles calculations
Nonradiative multiphonon theory
Analysis of electronic structures and carrier capture dynamics.
Both donor and acceptor levels of PtSi show large capture cross sections for charge carriers.
Capture cross sections vary with different configurations of PtSi, particularly with Jahn–Teller distortions.
Calculated cross sections align with experimental values when considering D2d configurations.
