Graphene as transparent electrode for direct observation of hole photoemission from silicon to oxide

(author unknown)



Rusen Yan, Qin Zhang, and Oleg A. Kirillov et al.

We demonstrate the application of graphene as collector material in internal photoemission (IPE) spectroscopy, which enables direct observation of both electron and hole injections at a Si/Al2O3 interface and overcomes the long-standing difficulty of detecting holes in IPE measurements. The observ ... [Appl. Phys. Lett. 102, 123106 (2013)] published Wed Mar 27, 2013.
