Impact of Nickel Diffusion on Leakage Current Degradation in β‐Ga2O3 Schottky Barrier Diodes
Information &Functional Materials, EarlyView.The diffusion of Ni atoms during Schottky electrode fabrication induces localized stress defects in β‐Ga₂O₃ substrates, which act as primary reverse leakage pathways in SBDs. Elucidating this mechanism provides critical guidance for optimizing electrode composition in high‐performance β‐Ga₂O₃ electronics.

Gradual volatile memristor–based artificial neurons with high uniformity for neuromorphic computing
InfoScience, EarlyView.Schematic of leaky integrate‐and‐fire artificial neurons for MNIST image classification. Abstract Artificial neurons are pivotal for neuromorphic hardware, but the development of compact and uniform devices remains challenging. Conventional volatile memristors suffer from abrupt switching, which hinders spatiotemporal consistency.

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance
Macromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.

Physical Review E, 2021
The regularized class of lattice Boltzmann methods (LBMs) leverage the potency of the standard lattice-Bhatnagar-Gross-Krook method by filtering out spurious nonhydrodynamic moments from the moment space; this is achieved through evaluating regularized populations via a multiscale or a Hermite polynomial expansion approach. In this paper, we propose an

Lattices for the lattice Boltzmann method
Physical Review E, 2009A recently introduced theory of higher-order lattice Boltzmann models [Chikatamarla and Karlin, Phys. Rev. Lett. 97, 190601 (2006)] is elaborated in detail. A general theory of the construction of lattice Boltzmann models as an approximation to the Boltzmann equation is presented.

Axisymmetric lattice Boltzmann method
Physical Review E, 2008A lattice Boltzmann method is developed for incompressible axisymmetric flows. Both force and source or sink terms are incorporated into the lattice Boltzmann equation in a natural way, which is consistent in dimension with the lattice Boltzmann equation.

Rectangular lattice Boltzmann method
Physical Review E, 2010A set of rectangular lattice Boltzmann methods for fluid flows is developed. It is shown that reformulating local equilibrium distribution functions can result in the rectangular lattice Boltzmann models without the aid of an interpolation for shallow water equations, Navier-Stokes equations, and axisymmetric flow equations.

Finite-volume lattice Boltzmann method
Physical Review E, 1999We present a finite-volume formulation for the lattice Boltzmann method (FVLBM) based on standard bilinear quadrilateral elements in two dimensions. The accuracy of this scheme is demonstrated by comparing the velocity field with the analytical solution of the Navier-Stokes equations for time dependent rotating Couette flow and Taylor vortex flow.
