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…
Violation of the Wiedemann-Franz law and ultra-low thermal conductivity of TiCT MXene
Yubin Huang, Jean Spiece, Tetiana Parker +3
The high electrical conductivity and good chemical stability of MXenes offer hopes for their use in many applications, such as wearable electronics, energy storage, or electromagne…
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…
Record-high Anomalous Ettingshausen effect in a micron-sized magnetic Weyl semimetal on-chip cooler
Mohammadali Razeghi, Jean Spiece, Valentin Fonck +8
Solid-state cooling devices offer compact, quiet, reliable and environmentally friendly solutions that currently rely primarily on the thermoelectric (TE) effect. Despite more than…
