Direct Observation of Acoustic Phonon Confinement in Free-Standing Semiconductor Nanowires
Fariborz Kargar, Bishwajit Debnath, Kakko Joona-Pekko +5
Similar to electron waves, the phonon states in semiconductors can undergo changes induced by external boundaries. Modification of acoustic phonon spectrum in structures with perio…
Phonons and Thermal Transport in Graphene and Graphene-Based Materials
Denis L. Nika, Alexander A. Balandin
A discovery of the unusual thermal properties of graphene stimulated experimental, theoretical and computational research directed at understanding phonon transport and thermal con…
Breakdown Current Density in BN-Capped Quasi-1D TaSe3 Metallic Nanowires: Prospects of Interconnect Applications
Maxim A. Stolyarov, Guanxiong Liu, Matthew A. Bloodgood +7
We report results of investigation of the current-carrying capacity of nanowires made from the quasi-1D van der Waals metal tantalum triselenide capped with quasi-2D boron nitride.…
Thermal Conductivity of Suspended Graphene with Defects
Hoda Malekpour, Pankaj Ramnani, Srilok Srinivasan +5
We investigate the thermal conductivity of suspended graphene as a function of the density of defects, ND, introduced in a controllable way. Graphene layers are synthesized using c…
Thermal Conductivity of Segmented Nanowires
Denis L. Nika, Aleksandr I. Cocemasov, Alexander A. Balandin
We present a review of the phonon thermal conductivity of segmented nanowires focusing on theoretical results for Si and Si/Ge structures with the constant and periodically modulat…
Thermal Transport in Graphene, Few-Layer Graphene and Graphene Nanoribbons
Denis L. Nika, Alexander A. Balandin
The discovery of unusual heat conduction properties of graphene has led to a surge of theoretical and experimental studies of phonon transport in two-dimensional material systems.…
