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…
Electroluminescence of monolayer WS in a scanning tunneling microscope: the effect of bias polarity on the spectral and angular distribution of the emitted light
Ricardo Javier Peña Román}, Delphine Pommier, Rémi Bretel +12
Inelastic electron tunneling in a scanning tunneling microscope (STM) is used to generate excitons in monolayer tungsten disulfide (WS). Excitonic electroluminescence is measur…
