Inelastic Light Scattering Spectroscopy of Magnons and Phonons in Nickel Oxide: Effects of Temperature
M. M. Lacerda, F. Kargar, E. Aytan +7
We report results of an investigation of the temperature dependence of the magnon and phonon frequencies in NiO. A combination of Brillouin - Mandelstam and Raman spectroscopies al…
Magnetic and Thermal Transport Properties of Permanent Magnets with Anisotropic Grain Structure
A. D. Volodchenkov, S. Ramirez, R. Samnakay +4
Nanostructured permanent magnets are gaining increasing interest and importance for applications such as generators and motors. Thermal management is a key concern since performanc…
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.…
The Commensurate-Incommensurate Charge-Density-Wave Transition and Phonon Zone Folding in 1T-TaSe2 Thin Films
R. Samnakay, D. Wickramaratne, T. R. Pope +3
Bulk 1T-TaSe2 exhibits unusually high charge density wave (CDW) transition temperatures of 600 K and 473 K below which the material exists in the incommensurate (I-CDW) and the com…
Low-Frequency 1/f Noise in MoS2 Thin-Film Transistors: Comparison of Single and Multilayer Structures
S. L. Rumyantsev, C. Jiang, R. Samnakay +2
We report on the transport and low-frequency noise measurements of MoS2 thin-film transistors with "thin" (2-3 atomic layers) and "thick" (15-18 atomic layers) channels. The back-g…
High-Temperature Performance of MoS2 Thin-Film Transistors: DC and Pulse Current-Voltage Characteristics
C. Jiang, S. L. Rumyantsev, R. Samnakay +2
The measurements of the high - temperature current - voltage characteristics of MoS2 thin - film transistors show that the devices remain functional to temperatures of at least as…
Selective Chemical Vapor Sensing with Few-Layer MoS2 Thin-Film Transistors
R. Samnakay, C. Jiang, S. L. Rumyantsev +2
We demonstrated selective gas sensing with MoS2 thin-film transistors using the change in the channel conductance, characteristic transient time and low-frequency current fluctuati…
Low-Frequency 1/f Noise in Molybdenum Disulfide Transistors
J. Renteria, R. Samnakay, S. L. Rumyantsev +3
We report on the results of the low-frequency (1/f, where f is frequency) noise measurements in MoS2 field-effect transistors revealing the relative contributions of the MoS2 chann…
All-Metallic Electrically-Gated Tantalum Diselenide Switches and Logic Circuits
J. Renteria, R. Samnakay, C. Jiang +8
We report the fabrication and performance of all-metallic three-terminal devices with tantalum diselenide thin-film conducting channels. For this proof-of-concept demonstration, th…
