Persistent hot carrier diffusion in boron arsenide single crystals imaged by ultrafast electron microscopy
Usama Choudhry, Fengjiao Pan, Taeyong Kim +6
Cubic boron arsenide (BAs) is promising for microelectronics thermal management due to its high thermal conductivity. Recently, its potential as an optoelectronic material is also…
Origin of high thermal conductivity in disentangled ultra-high molecular weight polyethylene films: ballistic phonons within enlarged crystals
Taeyong Kim, Stavros X. Drakopoulos, Sara Ronca +1
The thermal transport properties of oriented polymers are of fundamental and practical interest. High thermal conductivities ( WmK) have recently been rep…
Tutorial: Characterizing Microscale Energy Transport in Materials with Transient Grating Spectroscopy
Usama Choudhry, Taeyong Kim, Melanie Adams +3
Microscale energy transport processes are crucial in microelectronics, energy harvesting devices, and emerging quantum materials. To study these processes, methods that can probe t…
Origin of micron-scale propagation lengths of heat-carrying acoustic excitations in amorphous silicon
Taeyong Kim, Jaeyun Moon, Austin J. Minnich
The heat-carrying acoustic excitations of amorphous silicon are of interest because their mean free paths may approach micron scales at room temperature. Despite extensive investig…
