Electrical conductivity of crack-template-based transparent conducting films: mean-field approximation, effective medium theory, and simulation

This paper evaluates the accuracy of mean-field approximation and effective medium theory in modeling the electrical conductivity of crack-template-based transparent conducting films, finding that these methods can significantly overestimate conductivity due to the structural complexities of Poisson–Voronoi networks.

Nitrogen doping induced metal-insulator transition with iso-symmetric character in rutile VO2

This study demonstrates that in-situ nitrogen doping in epitaxial rutile VO2\text{VO}_2 thin films enables an iso-symmetric metal-insulator transition by suppressing V-V dimerization, resulting in faster switching speeds and providing a new strategy for tailoring phase transitions in correlated oxides.

Atomistic Mechanisms of Temperature-Dependent Ion Track Formation in Gallium Nitride under Swift Heavy Ion Irradiation

This study uses a coupled two-temperature model and molecular dynamics simulations to reveal that increasing temperature drives a morphological transition in GaN ion tracks from discontinuous segments to continuous channels, a process characterized by the atomic-scale decomposition of GaN into Ga clusters and N2N_2 bubbles and the nucleation of zincblende nanodomains linked to dislocation networks.

Complementary-polarity double-layer LiTaO3 resonators for symmetry-selective SH2 excitation with ultrahigh electromechanical coupling (kt^2 = 25.7%)

This paper reports a novel double-layer lithium tantalate (LiTaO3) bulk acoustic resonator using complementary-polarity films that achieves an ultrahigh electromechanical coupling coefficient of kt2=25.7%k_t^2 = 25.7\% through symmetry-selective excitation of the SH2 mode.

Step- and terrace-resolved crystal truncation rod scattering from vicinal surfaces under coherent heteroepitaxy

This paper develops a unified theoretical framework for crystal truncation rod (CTR) scattering from vicinal surfaces under coherent heteroepitaxy, demonstrating that non-specular rods can sensitively probe full elastic distortions, such as shear-induced triclinic deformation, while maintaining the ability to resolve step- and terrace-level structural and kinetic information during growth.
