Fluctuation-Controlled Asymmetric Kinetics in Metal-Insulator Transitions
Tapas Bar, David Pesquera, Timm Swoboda +5
We report asymmetric kinetics in thermally driven metal-insulator transitions (MITs) in 1T-TaS. Using combined transport, calorimetric, and Raman measurements, we show that the…

Domain-induced control of latent heat in freestanding BaTiO membranes
Tapas Bar, David Pesquera, Arnau Villalobos-Martin +11
Thin ferroelectric BaTiO films often exhibit continuous transitions instead of the first-order behavior of bulk crystals, a discrepancy usually attributed to epitaxial strain o…

Microsecond-Pulsed Nanocalorimetry: A Scalable Approach for Ultrasensitive Heat Capacity Measurements
Hugo Gómez-Torres, Manel Molina-Ruiz, Simone Privitera +6
We introduce a nanocalorimetric technique based on microsecond-pulsed heating (μs-PHnC) that enables high-sensitivity, quasi-isothermal heat capacity measurements on nanoscale samp…
