Optical characterization of heavy-ion induced damage in 4H-SiC
The interaction between silicon carbide and heavy ions is governed by both the material properties of SiC and the characteristics of the heavy ions. Relevant heavy-ion parameters include the total sto...
Low-frequency broadband absorber with porous material-coupled convoluted resonant cavity
Low-frequency noise exhibits strong penetration capability, while traditional sound-absorbing materials show limited performance in the low-frequency range. To address this issue, a sound-absorbing st...
Morphology, structure, and magnetic properties of <i>L</i> 10-FePt/Tb bilayers upon post-annealing
L 1 0 -FePt is the most important alloy in modern high-density heat-assisted magnetic recording (HAMR) media. In order to increase its bit stability and reach higher bit density, an increase of coerci...
Anomalous Klein tunneling with magnetic barriers in strained graphene
We study electron transport in a strained graphene sheet subjected to a sequence of N electrostatic and magnetic barriers. Employing a modified and improved transfer-matrix framework, we examine how t...
First-principles exploration of the impact of [Si—C] and [N=C] bonds in SiCN films: Composition, structure, and properties
Silicon carbon nitride (SiCN) is a ceramic material known for its exceptional thermal stability, chemical resistance, and mechanical strength. Compared to silicon nitride (Si3N4), SiCN offers enhanced...
Artificial synapse based on ULTRARAM memory device for neuromorphic applications
The memory demands of large-scale deep neural networks (DNNs) require synaptic weight values to be stored and updated in off-chip memory, such as dynamic random-access memory, which reduces energy eff...
Investigation of thermal conductivity of monolayer MoS2 supported on PDMS substrates with varying adhesion under different tensile strains
Atomically thin molybdenum disulfide (MoS2) has emerged as a promising candidate for next-generation flexible electronic devices due to its exceptional physical properties. However, in practical appli...
Modeling the contributions to acoustic nonlinearity from complex dislocation networks using 3D dislocation dynamics
Nonlinear ultrasonic parameters are highly sensitive to microstructural features that affect macroscale material behavior, providing a nondestructive means to characterize their evolution. Although di...
Study of carrier-mediated photothermal dynamics in a silicon wafer
The interplay between plasma and thermal transport phenomena in semiconductors under optical excitation is fundamental to optoelectronics and forms the physical basis of photothermal and photoacoustic...
Time-periodic electroosmotic flow and solute dispersion in a slip-regulated microchannel conveying Maxwell viscoelastic fluid
Electrokinetic transport and solute dispersion have key roles in microfluidic mixing and detection analysis. Dispersion of solutes is highly dependent upon the flow field, bringing in the importance o...
Tunable electronic properties of κ-(Al, In)2O3/Ga2O3 digital alloys via superlattice design
κ-Ga2O3-based digital-alloy superlattices offer a promising alternative to traditional random alloys for high performance heterostructure devices. Using density functional theory, we model (Al2O3/κ-Ga...
Molecular beam epitaxy and characterization of wurtzite InScN
We report the molecular beam epitaxial growth and characterization of wurtzite InScN thin films. We find that wurtzite InScN can be grown on GaN substrates under metal-rich conditions, resulting in sm...
