Direct measurement of the local electrocaloric effect in 2D ferroelectric InSe by Scanning Electrocaloric Thermometry
Jean Spièce, Valentin Fonck, Charalambos Evangeli +3
The electrocaloric effect refers to the temperature change in a material when an electric field is applied or removed. Significant breakthroughs revealed its potential for solid-st…
Mapping Conductance and Switching Behavior of Graphene Devices In Situ
Ondrej Dyck, Jacob L. Swett, Charalambos Evangeli +3
Graphene has been proposed for use in various nanodevice designs, many of which harness emergent quantum properties for device functionality. However, visualization, measurement, a…
Contrast mechanisms in secondary electron e-beam induced current (SEEBIC) imaging
Ondrej Dyck, Jacob L. Swett, Charalambos Evangeli +3
Over the last few years, a new mode for imaging in the scanning transmission electron microscope (STEM) has gained attention as it permits the direct visualization of sample conduc…
Charge-state dependent vibrational relaxation in a single-molecule junction
Xinya Bian, Zhixin Chen, Jakub K. Sowa +8
The interplay between nuclear and electronic degrees of freedom strongly influences molecular charge transport. Herein, we report on transport through a porphyrin dimer molecule, w…
Single-electron transport in a molecular Hubbard dimer
James O. Thomas, Jakub K. Sowa, Bart Limburg +9
Many-body electron interactions are at the heart of chemistry and solid-state physics. Understanding these interactions is crucial for the development of molecular-scale quantum an…
Direct Mapping of Local Seebeck Coefficient in 2D Material Nanostructures via Scanning Thermal Gate Microscopy
Achim Harzheim, Charalambos Evangeli, Oleg V. Kolosov +1
Local variations in the Seebeck coefficient in low-dimensional materials-based nanostructures and devices play a major role in their thermoelectric performance. Unfortunately, curr…
Efficient heating of single-molecule junctions for thermoelectric studies at cryogenic temperatures
