Enhanced photoemission performance of an AlGaN photocathode by a superlattice emission layer
AIP Advances, 2023 The AlGaN photocathode with a superlattice emission layer was grown by metal organic chemical vapor deposition. The existence of the superlattice structure was confirmed using a transmission electron microscope, and its optical and electrical properties ...

A Method to Probe the Interfaces in La2−xSrxCuO4-LaSrAlO4-La2−xSrxCuO4 Trilayer Junctions
Condensed Matter, 2023 C-axis trilayer cuprate Josephson junctions are essential for basic science and digital circuit applications of high-temperature superconductors. We present a method for probing the interface perfection in La2−xSrxCuO4 (LSCO)-LaSrAlO4 (LSAO)-La2−xSrxCuO4

Effect of the strain on spin-valley transport properties in MoS2 superlattice
Scientific Reports, 2021 The effect of the strain on the spin and valley dependent transport properties, including the conductance and polarization, through a monolayer MoS2 superlattice under Rashba spin–orbit coupling is theoretically investigated.

Characterization of temperature-dependent superlattice in Cu:KTN crystal
Materials Research Express, 2020 In this study, we grew CuO doped potassium tantalum niobate (Cu:KTN) crystals with a uniform superlattice structure by the off-center top-seeded solution growth (TSSG) method.

Suppression of coherent thermal transport in quasiperiodic graphene-hBN superlattice ribbons [PDF]
Carbon, 2020 Nanostructured superlattices are promising materials for novel electronic devices due to their adjustable physical properties. Periodic superlattices facilitate coherent phonon thermal transport due to constructive wave interference at the boundaries ...

PEROVSKITES AND OTHER FRAMEWORK STRUCTURE CRYSTALLINE MATERIALS (BOOK' FIRST PAGES AND PREFACE)
Materials and Devices, 2021 Perovskites are among the most famous materials due to their exceptional properties: they present nearly all existing types of interesting properties, in particular as ferroics or multiferroics, they may be insulators, (super)conductors, or ...

All-angle broadband ENZ metamaterials
New Journal of Physics, 2022 A novel type of metamaterial is presented to produce broadband near-zero effective permittivity to a defined polarized probing electromagnetic wave with varying angles of incidence. The metamaterial has a uniaxial unit cell structure made up of symmetric

Terahertz superlattice parametric oscillator [PDF]
, 2005 We report a GaAs/AlAs superlattice parametric oscillator. It was pumped by a microwave field (power few mW) and produced 3rd harmonic radiation (frequency near 300 GHz).

Manipulating matter waves in an optical superlattice [PDF]
, 2016 We investigate the potential for controlling a non-interacting Bose-Einstein condensate loaded into a one-dimensional optical superlattice. Our control strategy combines Bloch oscillations originating from accelerating the lattice and from time-dependent
