Anomalous Raman Spectra and Thickness Dependent Electronic properties of WSe2
H. Sahin, S. Tongay, S. Horzum +5
Typical Raman spectra of transition metal dichalcogenides (TMDs) display two prominent peaks, E2g and A1g, that are well separated from each other. We find that these modes are deg…

Phonon Softening and Direct to Indirect Bandgap Crossover in Strained Single Layer MoSe2
S. Horzum, H. Sahin, S. Cahangirov +4
Motivated by recent experimental observations of Tongay et al. [Tongay et al., Nano Letters, 12(11), 5576 (2012)] we show how the electronic properties and Raman characteristics of…
