Journal ArticleDOI
Propagating elastic vibrations dominate thermal conduction in amorphous silicon
TL;DR: In this paper, the authors present a lattice and molecular dynamics analysis of vibrations in amorphous solids that supports a qualitatively different picture in which propagating elastic waves dominate the thermal conduction and are scattered by local fluctuations of elastic modulus rather than anharmonicity.
Journal ArticleDOI
Intrinsic anharmonic localization in thermoelectric PbSe.
Michael Manley,Olle Hellman,Nina Shulumba,Andrew F. May,P. Stonaha,Jeffrey W. Lynn,Vasile O. Garlea,Ahmet Alatas,Raphaël P. Hermann,John D. Budai,Hong Wang,Brian C. Sales,Austin J. Minnich +12 more
TL;DR: This study shows how nonlinear physics beyond conventional anharmonic perturbations can fundamentally alter vibrational transport properties of lead chalcogenides.
Journal ArticleDOI
Importance of frequency-dependent grain boundary scattering in nanocrystalline silicon and silicon–germanium thermoelectrics
Chengyun Hua,Austin J. Minnich +1 more
TL;DR: In this article, the impact of frequency-dependent grain boundary scattering in nanocrystalline silicon and silicon-germanium alloys in a realistic 3D geometry using frequencydependent variance-reduced Monte Carlo simulations was examined.
Journal ArticleDOI
Ultralow Thermal Conductivity and Mechanical Resilience of Architected Nanolattices
Nicholas G. Dou,Robert A. Jagt,Robert A. Jagt,Carlos M. Portela,Julia R. Greer,Austin J. Minnich +5 more
TL;DR: This work reports that nanolattices composed of 24- to 182-nm-thick hollow alumina beams in the octet-truss architecture achieved thermal conductivities as low as 2 mW m-1 K-1 at room temperature while maintaining specific stiffnesses of 0.3 to 3 MPa kg-1 m3 and the ability to recover from large deformations.
Journal ArticleDOI
Spatial-Temporal Imaging of Anisotropic Photocarrier Dynamics in Black Phosphorus
Bolin Liao,Huan Zhao,Ebrahim Najafi,Xiaodong Yan,He Tian,Jesse Tice,Austin J. Minnich,Han Wang,Ahmed H. Zewail +8 more
TL;DR: In this paper, the authors used the newly developed scanning ultrafast electron microscopy (SUEM) to directly visualize the motion of photoexcited hot carriers on the surface of BP in both space and time.
