Signature of Many-Body Localization of Phonons in Strongly Disordered Superlattices
Thanh Nguyen, Nina Andrejevic, Hoi Chun Po +17
Many-body localization (MBL) has attracted significant attention due to its immunity to thermalization, role in logarithmic entanglement entropy growth, and opportunities to reach…
Size-dependent lattice dynamics of atomically precise cadmium selenide quantum dots
Chenyang Shi, Alexander N. Beecher, Yan Li +5
Material properties depend sensitively on the atomic arrangements and atomic bonding, but these are notoriously difficult to measure in nanosized atomic clusters due to the small s…
Rare earth size dependence on structural, electronic and magnetic properties of R2NiMnO6 double perovskites
Mohd Nasir, Sunil Kumar, N. Patra +8
Rare earth Manganite Nickelite double perovskites are prepared by solgel assisted combustion route, where, R varies from La, Pr, Nd, Sm, Gd, Tb, Dy, Y, and Ho. The samples have bee…
Frequency dependent dielectric properties of Al/ maleic anhydride (MA) /p-Si structures
S. Bilge Ocak, A. B. Selçuk, S. B. Bayram +1
Al/ maleic anhydride (MA) /p-Si organic Schottky devices were fabricated on a p-Si semiconductor wafer by spin coating. The frequency and voltage dependent dielectric constant of A…
Imaging and optical properties of single core-shell GaAs-AlGaAs nanowires
Thang B. Hoang, L. V. Titova, H. E. Jackson +5
We study the optical properties of a single core-shell GaAs-AlGaAs nanowire (grown by VLS method) using the technique of micro-photoluminescence and spatially-resolved photolumines…
Temperature dependent photoluminescence of single CdS nanowires
Thang Ba Hoang, L. V. Titova, H. E. Jackson +4
Temperature dependent photoluminescence (PL) is used to study the electronic properties of single CdS nanowires. At low temperatures, both near-band edge (NBE) photoluminescence (P…
