Thermal transport evolution due to nanostructural transformations in Ga-doped indium-tin-oxide thin films
Alexandr Cocemasov, Vladimir Brinzari, Do-Gyeom Jeong +4
We report on a comprehensive theoretical and experimental investigation of thermal conductivity in indium-tin-oxide (ITO) thin films with various Ga concentrations (0-30 at. %) dep…
Energetic, structural and electronic features of Sn-, Ga-, O-based defect complexes in cubic In2O3
Alexandr I. Cocemasov, Vladimir I. Brinzari, Denis L. Nika
Defect energy formation, lattice distortions and electronic structure of cubic In2O3 with Sn, Ga and O impurities were theoretically investigated using density functional theory. D…
Thermal transport in semiconductor nanostructures, graphene and related two-dimensional materials
Alexandr I. Cocemasov, Calina I. Isacova, Denis L. Nika
We review experimental and theoretical results on thermal transport in semiconductor nanostructures (multilayer thin films, core/shell and segmented nanowires), single- and few-lay…
Ultra-low Thermal Conductivity of Nanogranular Indium Tin Oxide Films Deposited by Spray Pyrolysis
Vladimir I. Brinzari, Alexandr I. Cocemasov, Denis L. Nika +1
The authors have shown that nanogranular indium tin oxide (ITO) films, deposited by spray pyrolysis on silicon substrate, demonstrate ultralow thermal conductivity ~ 0.84 +/-0.12 W…
Phonon Engineering of the Specific Heat of Twisted Bilayer Graphene: The Role of the Out-of-Plane Phonon Modes
Alexandr I. Cocemasov, Denis L. Nika, Alexander A. Balandin
We investigated theoretically the specific heat of graphene, bilayer graphene and twisted bilayer graphene taking into account the exact phonon dispersion and density of states for…
Specific Heat of Twisted Bilayer Graphene
Denis L. Nika, Alexandr I. Cocemasov, Alexander A. Balandin

Thermal Conductivity Inhibition in Phonon Engineered Core-Shell Cross-Section Modulated Si/Ge Nanowires
Denis L. Nika, Alexandr I. Cocemasov, Dmitrii V. Crismari +1
We have shown theoretically that a combination of cross-section modulation and acoustic mismatch in the core-shell Si/Ge nanowires can lead to a drastic reduction of the thermal co…
Phonons in Twisted Bilayer Graphene
Alexandr I. Cocemasov, Denis L. Nika, Alexander A. Balandin
We theoretically investigated phonon dispersion in AA-stacked, AB-stacked and twisted bilayer graphene with various rotation angles. The calculations were performed using the Born-…
