Low-Frequency Current Fluctuations in Graphene-like Exfoliated Thin-Films of Topological Insulators
M. Z. Hossain, S. L. Rumyantsev, K. M. F. Shahil +3
We report on the low-frequency current fluctuations and electronic noise in thin-films made of bismuth selenide topological insulators. The films were prepared via the graphene-lik…
Tuning of Graphene Properties via Controlled Exposure to Electron Beams
G. Liu, D. Teweldebrhan, A. A. Balandin
Controlled modification of graphene properties is essential for its proposed electronic applications. Here we describe a possibility of tuning electrical properties of graphene via…
Large-Area High-Throughput Identification and Quality Control of Graphene and Few-Layer Graphene: Prospects of Industry-Scale Applications
Craig M. Nolen, Giovanni Denina, Desalegne Teweldebrhan +2
Practical applications of graphene require a reliable high-throughput method of graphene identification and quality control, which can be used for large-scale substrates and wafers…
1/f Noise in Thin Films of Topological Insulator Materials
M. Zahid Hossain, Sergey L. Rumyantsev, Desalegne Teweldebrhan +3
We report results of investigation of the low-frequency excess noise in device channels made from topological insulators - a new class of materials with a bulk insulating gap and c…
Mechanically-Exfoliated Stacks of Thin Films of Bismuth Telluride Topological Insulators with Enhanced Thermoelectric Performance
Vivek Goyal, Desalegne Teweldebrhan, Alexander A. Balandin
We report on "graphene-like" mechanical exfoliation of single-crystal Bi2Te3 films and thermoelectric characterization of the stacks of such films. Thermal conductivity of the resu…
From Graphene to Bismuth Telluride: Mechanical Exfoliation of Quasi-2D Crystals for Applications in Thermoelectrics and Topological Insulators
Desalegne Teweldebrhan, Vivek Goyal, Alexander A. Balandin
Bismuth telluride (Bi2Te3) and its alloys are the best bulk thermoelectric materials known today. The stacked quasi-two-dimensional (2D) layers of Bi2Te3 were also identified as to…
