A cesium-iodide surface treatment for enhancement of negative electron affinity photocathode chemical robustness
Photocathodes activated to negative electron affinity with a cesium-based activation layer, such as GaAs and GaN, can be used for generating spin-polarized electron beams, but their extreme sensitivit...
Phase relations of semiconductors SnSe and GeSe at high pressures and high temperatures
The group IV–VI monochalcogenides have attracted widespread attention because of their rich structural characteristics and diverse physical properties. SnSe and GeSe, as typical IV–VI monochalcogenide...
On La-doped HZO as a high-<i>k</i> dielectric for DRAM: Low EOT and approaches for its improvement
Despite the great potential of the hafnium zirconium oxide (HZO)-based ferroelectrics for the emerging non-volatile ferroelectric memories, it provides also a material solution to the existing technol...
Study of Ti/TiO2/Ti selector for the memristive crossbar array
Selectors are non-linear elements used in memristor circuits. We explore a Ti/TiO2/Ti selector as part of a one-selector–one-resistor memristor for high-density crossbar arrays. The Ti/TiO2/Ti stack i...
Fundamental advantages of multijunction thermoradiative cells
Thermoradiative (TR) cells convert heat to work through emission of thermal radiation. Multijunction thermoradiative cells have received little research interest due to the apparent overlap with energ...
The electroviscous effect on time-periodic pressure-driven flow in a pH-regulated slit nanochannel
The surface charge plays a crucial role in electrokinetic flow within micro/nanochannels. The charge on silica surfaces originates from the protonation and deprotonation of the silanol functional grou...
Spanwise spreading of gypsum slurry during deposition on the belt under a roller
An experimental setup was designed and built to explore the spreading of a slurry layer during deposition on a moving belt before a rotating roller. The case of the water-to-stucco ratio of 75 was stu...
Kinetic Monte Carlo simulation reveals defect charge accumulation favoring ferroelectric phase formation in Hf1−<i>x</i>Zr<i>x</i>O2 thin films
Charged oxygen vacancies are thought to be responsible for fatigue effects in HfO2- and ZrO2-based ferroelectrics, while also supporting the formation of the ferroelectric phase. We investigate the po...
Lattice thermal conductivity of 16 elemental metals from molecular dynamics simulations with a unified neuroevolution potential
Metals play a crucial role in heat management in electronic devices, such as integrated circuits, making it vital to understand heat transport in elementary metals and alloys. In this work, we systema...
Non-invasive single-shot wide-field imaging through dynamic thick scattering media base on a fully developed speckle pattern
Imaging through scattering media has always been a challenge to be solved in optical applications. The speckle autocorrelation method has achieved great success in non-invasive single-shot imaging thr...
Deep reinforcement learning unveils ternary nanocluster configurations: A case study on Ag6Pd5Cu4
The identification of global minimum configurations in ternary nanoclusters faces challenges due to the inherent complexity of multimetallic potential energy surfaces. Traditional methods, such as gen...
Unveiling negative capacitance in ferroelectric heterostructures: A 3D energy landscape perspective
Although negative capacitance (NC) holds promise to overcome the Boltzmann tyranny, it is still subjected to debate due to the lack of a self-consistent, thermodynamic description. Herein, a 3D energy...
Enhancing electrical properties of BiFeO3-based thin films via introducing VO2 overlayers with double-interface charge barrier
Developing high-performance lead-free ferroelectric materials is a significant challenge for flexible electronics and high-temperature memory applications. However, the high leakage current and poor e...
Optical gain evolution and quantum-to-bulk transition in wide AlGaN quantum wells
We present a theoretical study of the optical gain characteristics in wide Al0.8Ga0.2N quantum wells (QWs) designed for ultraviolet C emission strained to AlN substrates. The electronic band structure...
Continuum shock mixture models for Ni+Al multilayers: Inert mesoscale simulations
Mesoscale modeling of shock waves in Ni+Al multilayers poses significant challenges that are due, in part, to shock-induced chemical reactions. Current modeling approaches utilize reactive molecular d...
