DOI: 10.1038/s41598-017-04987-w
Abstract: We study the interaction between localized vibrational modes and propagating phonons in graphene nanoribbons with different types of localized internal and edge defects. We analyze discrete eigenmodes of the nanoribbons with defects and also employ… read more here.

DOI: 10.1109/jphotov.2020.2978060
Abstract: A lot of effort is required in order to close the efficiency gap between laboratory record Cu(In,Ga)Se2 (CIGS) solar cells and commercially produced modules. An obstacle easily overlooked is the fact that reduced module performance… read more here.
