Size-Dependent Luminescence Properties of Chromatographically-Separated Graphene Quantum Dots
Naoto Fuyuno, Daichi Kozawa, Yuhei Miyauchi +6
We studied the photoluminescence (PL) properties of graphene quantum dots (GQDs) separated by size-exclusion high performance liquid chromatography. The size separation of GQDs was…
Fabrication of single-walled carbon nanotube/Si heterojunction solar cell with high photovoltaic conversion efficiency and stability
Feijiu Wang, Daichi Kozawa, Yuhei Miyauchi +4
The photovoltaic properties of carbon nanotube/Si heterojunction solar cells were investigated using network films of high quality single-walled carbon nanotubes (SWNTs) grown by a…
Tunable Photoluminescence of Monolayer MoS2 via Chemical Doping
Shinichiro Mouri, Yuhei Miyauchi, Kazunari Matsuda
We demonstrate the tunability of the photoluminescence (PL) properties of monolayer (1L)-MoS2 via chemical doping. The PL intensity of 1L-MoS2 was drastically enhanced by the adsor…
