Triboelectricity has been known since antiquity, but the fundamental physics underlying this phenomenon lacks consensus. We present a flexoelectric model for triboelectricity where contact deformation induced band bending is the driving force for charge transfer. This framework is combined with first principles and finite element calculations to explore charge transfer implications for different contact geometry and materials combinations. We demonstrate that our ab initio based formulation is compatible with existing empirical models and experimental observations including charge transfer between similar materials and size/pressure dependencies associated with triboelectricity. |
