Sub-diffraction-resolved spatial distribution of emitting excitons in STM-induced luminescence of 2D semiconductors via Richardson-Lucy deconvolution
Elysé Laurent, Ricardo Javier Peña Román, Sarah Miller +7
Using scanning tunneling microscopy-induced luminescence (STML), the optical properties of two-dimensional (2D) semiconductors may be investigated at the nanoscale. This is possibl…
Ambient-Induced Selenium Segregation and Nanoparticle Formation in 2H-HfSe2: An Experimental and Theoretical Study
Stefany P. Carvalho, Guilherme S. L. Fabris, Ana Carolina F. de Brito +7
We investigate the air-induced degradation of few-layer hafnium diselenide (HfSe) through combined experimental and theoretical approaches. AFM and SEM reveal the formation of…
Impacts of dielectric screening on the luminescence of monolayer WSe
Fabio J. R. Costa, Thiago G-L. Brito, Ingrid D. Barcelos +1
Single layers of transition metal dichalcogenides, such as WSe have gathered increasing attention due to their intense electron-hole interactions, being considered promising ca…
eV electron spectromicroscopy using free-space light
Yves Auad, Eduardo J. C. Dias, Marcel Tencé +7
The synergy between free electrons and light has recently been leveraged to reach an impressive degree of simultaneous spatial and spectral resolution, enabling applications in mic…
Design and implementation of a device based on an off-axis parabolic mirror to perform luminescence experiments in a scanning tunneling microscope
Ricardo Javier Peña Román, Yves Auad, Lucas Grasso +5
We present the design, implementation, and illustrative results of a light collection/injection strategy based on an off-axis parabolic mirror collector for a low-temperature Scann…
Tunneling-current-induced local excitonic luminescence in p-doped WSe monolayers
Ricardo Javier Peña Román, Yves Auad, Lucas Grasso +3
We have studied the excitonic properties of exfoliated tungsten diselenide (WSe) monolayers transferred to gold substrates using the tunneling current in a Scanning Tunneling M…
