Anomalous thermal and elastic properties of an epitaxial NiTi film exhibiting R-phase
Kristýna RepÄek, Tomáš Grabec, David MareÅ¡ +8
Shape memory alloys like NiTi are at the core of emerging thermal management applications, including elastocaloric refrigeration, thermoelastic harvesting, and latent heat storage.…
Study of the acoustic and thermal response of an elastically anisotropic solid to a sub-nanosecond laser pulse in transient grating spectroscopy
Jakub KuÅ¡nÃr, Tomáš Grabec, Petr Sedlák +2
Transient grating spectroscopy (TGS) is a material characterization technique based on laser-induced thermoelastic excitation of thermal and acoustic gratings. On opaque samples, t…
Ultra-transient grating spectroscopy for visualization of surface acoustics
Tomáš Grabec, Pavla Stoklasová, Kristýna RepÄek +5
Ultrasonic wave propagation across material surfaces reveals essential information about the materials' elastic behavior. The elastodynamic response of the surface is characterized…
