Journal ArticleDOI
Properties of graphene produced by the high pressure-high temperature growth process
F. Parvizi,Desalegne Teweldebrhan,Subhasis Ghosh,Irene Calizo,Alexander A. Balandin,H. Zhu,Reza Abbaschian +6 more
TL;DR: In this paper, a new method for the synthesis of graphene, a mono-layer of carbon atoms arranged in a honey comb lattice, and the assessment of the properties of obtained graphene layers using micro-Raman characterisation was reported.
Journal ArticleDOI
Gating of Single‐Layer Graphene with Single‐Stranded Deoxyribonucleic Acids
Jian Lin,Desalegne Teweldebrhan,Khalid Ashraf,Guanxiong Liu,Xiaoye Jing,Zhong Yan,Rong Li,Mihri Ozkan,Roger K. Lake,Alexander A. Balandin,Cengiz S. Ozkan +10 more
TL;DR: Current-voltage measurements of the hybrid ssDNA/graphene system indicate a shift in the Dirac point and "intrinsic" conductance after ssDNA is patterned, and density functional theory calculations rule out significant charge transfer or modification of the graphene band structure in the presence of ssDNA fragments.
Journal ArticleDOI
Direct Low-Temperature Integration of Nanocrystalline Diamond with GaN Substrates for Improved Thermal Management of High-Power Electronics
TL;DR: In this paper, a novel approach for the direct synthetic diamond-GaN integration via deposition of the high-quality nanocrystalline diamond fi lms directly on GaN substrates at temperatures as low as 450-500 ° C is reported.
Journal ArticleDOI
Thermal properties of the optically transparent pore-free nanostructured yttria-stabilized zirconia
TL;DR: In this paper, the thermal conductivity of nanocrystalline yttria-stabilized zirconia was investigated and the pore-free bulk samples were prepared via the spark plasma sintering process to ensure homogeneity.
Journal ArticleDOI
Anomalous electron transport in back-gated field-effect transistors with TiTe2 semimetal thin-film channels
Javed M. Khan,Craig M. Nolen,Desalegne Teweldebrhan,Darshana Wickramaratne,Roger K. Lake,Alexander A. Balandin +5 more
TL;DR: In this article, the authors report on "graphene-like" mechanical exfoliation of thin films of titanium ditelluride and investigation of their electronic properties.
