The grain-size effect on thermal conductivity of uranium dioxide
K. Shrestha, T. Yao, J. Lian +4
We have investigated the grain boundary scattering effect on the thermal transport behavior of uranium dioxide (UO). The polycrystalline samples having different grain-sizes (0…
Thermal and transport properties of U3Si2
Daniel J. Antonio, Keshav Shrestha, Jason M. Harp +4
We have studied U_3Si_2 by means of the heat capacity, electrical resistivity, Seebeck and Hall effects, and thermal conductivity in the temperature range 2-300 K and in magnetic f…
On the magnetic and electronic properties of NpPdSn
K. Shrestha, D. Antonio, J-C. Griveau +5
We have studied NpPdSn by means of the heat capacity, electrical resistivity, Seebeck and Hall effect, Np Mössbauer spectroscopy, and neutron diffraction measurements in th…
Combination of thermal and electric properties measurement techniques in a single setup suitable for radioactive materials in controlled environments and based on the 3-omega approach
K. Shrestha, K. Gofryk
We have designed and developed a new experimental setup, based on the 3-omega method, to measure thermal conductivity, heat capacity and electrical resistivity of a variety of samp…
Weak antilocalization effect due to topological surface states in BiSeTe
K. Shrestha, D. Graf, V. Marinova +2
We have investigated the weak antilocalization (WAL) effect in the p-type BiSeTe topological system. The magnetoconductance shows a cusp-like feature at low mag…
Extremely large non-saturating magnetoresistance and ultrahigh mobility due to topological surface states in metallic Bi2Te3 topological insulator
K. Shrestha, M. Chou, D. Graf +3
Weak antilocalization (WAL) effects in Bi2Te3 single crystals have been investigated at high and low bulk charge carrier concentrations. At low charge carrier density the WAL curve…
Large magnetoresistance and Fermi surface study of SbSeTe single crystal
K. Shrestha, V. Marinova, D. Graf +2
We have studied the magnetotransport properties of a SbSeTe single crystal. Magnetoresistance (MR) is maximum when the magnetic field is perpendicular to the sample surface…
Simultaneous detection of quantum oscillations from bulk and topological surface states in metallic Bi2Se2.1Te0.9
Keshav Shrestha, David E. Graf, Vera Marinova +2
Shubnikov-de Haas (SdH) oscillations in metallic Bi2Se2.1Te0.9 are studied in magnetic fields up to 35 Tesla. It is demonstrated that two characteristic frequencies determine the q…
Quantum oscillations in metallic Sb2Te2Se topological insulator
K. Shrestha, V. Marinova, D. Graf +2
We have studied the magnetotransport properties of the metallic, p-type Sb2Te2Se which is a topological insulator. Magnetoresistance shows Shubnikov de Haas oscillations in fields…
Shubnikov-de Haas oscillations from topological surface states of metallic BiSeTe
Keshav Shrestha, Vera Marinova, Bernd Lorenz +1
We have studied the quantum oscillations in the conductivity of metallic, p-type BiSeTe. The dependence of the oscillations on the angle of the magnetic field w…
