Ultraviolet optical conductivity, exciton fine-structure and dispersion of freestanding monolayer h-BN
Jinhua Hong, Alberto Guandalini, Weibin Wu +7
Excitons govern the light-matter interaction in 2D gapped materials with intrinsically large binding energies. In spite of plentiful optical measurements in the visible for semicon…
Core-hole induced misalignment between Van-Hove singularities and K-edge fine structure in carbon nanotubes
Martin Unzog, Alexey Tal, Pedro Melo +4
We investigate the relationship between the K-edge fine structure of isolated single-wall carbon nanotubes (SWCNTs) and the Van Hove singularities (VHSs) in the conduction band den…
Excitonic effects in energy loss spectra of freestanding graphene
Alberto Guandalini, Ryosuke Senga, Yung-Chang Lin +8
In this work we perform electron energy-loss spectroscopy (EELS) of freestanding graphene with high energy and momentum resolution to disentangle the quasielastic scattering from t…
One-dimensional van der Waals Heterostructures: Growth Mechanism and Handedness Correlation Revealed by Non-destructive TEM
Yongjia Zheng, Akihito Kumamoto, Kaoru Hisama +15
In this work, we perform a follow-up and comprehensive study on the structural details and formation mechanism of chemical vapor deposition (CVD) synthesized one-dimensional (1D) v…
