In-plane anisotropy in biaxial ReS2 crystals probed by nano-optical imaging of waveguide modes
Fabian Mooshammer, Sanghoon Chae, Shuai Zhang +9
Near-field imaging has emerged as a reliable probe of the dielectric function of van der Waals crystals. In principle, analyzing the propagation patterns of subwavelength waveguide…
Near-Infrared plasmon induced hot electron extraction evidence in an indium tin oxide nanoparticle / monolayer molybdenum disulphide heterostructure
Michele Guizzardi, Michele Ghini, Andrea Villa +8
In this work, we observe plasmon induced hot electron extraction in a heterojunction between indium tin oxide nanocrystals and monolayer molybdenum disulphide. We study the sample…
Broadband optical parametric amplification by two-dimensional semiconductors
Chiara Trovatello, Andrea Marini, Xinyi Xu +11
Optical parametric amplification is a second-order nonlinear process whereby an optical signal is amplified by a pump via the generation of an idler field. It is the key ingredient…
