New dynamics observed in semiconductors!

Our group, in collaboration with researchers from Argonne National Lab and Northwestern University, have revealed a new dynamic that affects how doped semiconductors conduct charge: http://pubs.acs.org/doi/10.1021/acsnano.7b04414.  We used excited state X-ray absorption spectroscopy to demonstrate that the bonds of semiconductor dopants are altered when charge flows through them. Although this dynamic is detrimental to conduction, we proposed methods to minimize charge carrier modulation of the dopant bonding that will give rise to smarter, more energy efficient advanced nanomaterials for electronic devices.
