First-Principles Analysis of Cr-Doped SrTiO3 Perovskite as Optoelectronic Materials [PDF]

Iranian Journal of Materials Science and Engineering, 2023
This contribution evaluates the influence of Cr doping on the ground state properties of SrTiO3 Perovskite using GGA-PBE approximation. Results of the simulated model infer agreement with the previously published literature.

Nonlinear Transverse Transport in a Ferromagnetic Polar Metal

Advanced Electronic Materials, EarlyView.
This work reports the observation of a nonlinear transverse response in ferromagnetic polar SrRuO3(111) thin films. The nonlinear signal exhibits a sharp enhancement across the magnetic phase transition. Through detailed scaling and theoretical analysis, the authors attribute this behavior to a sign reversal of the Berry curvature triple, establishing ...

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

Angewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Light emission and magnetic properties of aluminum films grown on SrTiO3 by molecular beam epitaxy

AIP Advances, 2016
Aluminum films were grown on SrTiO3 (100) substrates using a plasma-assisted molecular beam epitaxy system. We found that the intensity of defect emission coming through the Al films was enhanced to two fold.

Implications of Transient Negative Capacitance Effect in Ferroelectric Polarization Dynamics

Advanced Electronic Materials, EarlyView.
Transient voltage artifacts observed during ferroelectric switching are shown to originate from measurement circuitry rather than intrinsic negative capacitance. By correlating switching current, time scale, and series resistance, this work establishes practical design rules for reliable pulse‐switching experiments and circuit integration of ...

Photoresponse dynamics in amorphous-LaAlO3/SrTiO3 interfaces [PDF]

, 2015
The time-resolved photoconductance of amorphous and crystalline LaAlO3/SrTiO3 interfaces, both hosting an interfacial 2-dimensional electron gas, is investigated under irradiation by variable-wavelengths, visible or ultraviolet photons.
