Quantum Heat Under the Microscope: A Perspective on Cryogenic Scanning Thermal Microscopy
Valentin Fonck, Jean Spiece, Pascal Gehring
Exploring thermal transport at cryogenic temperatures presents both significant challenges and valuable insights. By uncovering the thermal counterpart of well-known quantum phenom…
Direct Nanoscale Pyroelectric Characterization of a CuInPS van der Waals Nanogenerator
Valentin Fonck, Roop K. Mech, Mohammadali Razeghi +8
Pyroelectric energy conversion offers a route for harvesting time-dependent thermalfluctuations that are abundant in natural and technological environments. Twodimensional ferroele…
Thermal transport mapping in twisted double bilayer graphene
Roop Kumar Mech, Alessandra Canetta, Yubin Huang +13
Two-dimensional (2D) materials have attracted significant interest due to their tunable physical properties when stacked into homo- and hetero-structures. Twisting adjacent layers…
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…
Versatile polymer method to dry-flip two-dimensional moiré hetero structures for nanoscale surface characterization
Roop Kumar Mech, Jean Spièce, Kenji Watanabe +2
The recent discovery of magic angle twisted bilayer graphene (MATBG), in which two sheets of monolayer graphene are precisely stacked to a specific angle, has opened up a plethora…
Quantifying the local mechanical properties of twisted double bilayer graphene
Alessandra Canetta, Sergio Gonzalez-Munoz, Viet-Hung Nguyen +13
Nanomechanical measurements of minimally twisted van der Waals materials remained elusive despite their fundamental importance for device realisation. Here, we use Ultrasonic Force…
