1026. Making of efficient p-type GaN by plasma-assisted molecular beam epitaxy

Invited Speaker / Conférencier(ère) invité(e)

Efficient p-type doping remains a central challenge in GaN epitaxy and associated devices such as light-emitting diodes, laser diodes, photoelectrochemical cells as well as quantum devices. Plasma-assisted molecular beam epitaxy (PA-MBE) offers a compelling alternative to metal-organic vapor phase epitaxy (MOVPE) due to its intrinsic advantages in Mg incorporation and the absence of...

728. Experimental and numerical investigation of nanosecond discharges in air gap with hemispherical dielectric layer

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Electrical discharges are transient phenomena highly sensitive to the geometric and dielectric properties of their surrounding environment. Such a dependence directly influences plasma-surface interactions and the efficiency of a related application. This study investigates experimentally and by simulation the propagation dynamics of nanosecond discharge in air gap with the presence of a...

876. Effect of the chain of multiple water droplets on the propagation of a nanosecond pulsed plasma discharge at atmospheric pressure

Plasma Physics / Physique des plasmas (DPP)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Plasma–liquid interactions have attracted growing interest in both academia and industry [1] due to their relevance to chemical synthesis [2], microbial inactivation [3], and environmental remediation [4,5]. Discharges at atmospheric pressure are highly sensitive to nearby liquid structures, which can reshape their formation and propagation. In this work, we investigate how a chain of...

902. Strain Engineering in Epitaxial SrTiO₃ Thin Films Grown by Magnetron Sputtering on Vicinal MgO Substrates

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

SrTiO₃ (STO), a functional perovskite oxide, is dielectric at room temperature but can become ferroelectric under strain or doping. Here, STO thin films are grown epitaxially on MgO substrates with vicinal surfaces flat terraces, with RMS roughness on the order of tens of picometers. The lattice mismatch between MgO (~4.2 Å) and STO (~3.9 Å) results in a tensile strain of approximately 7.8%,...

680. Template-Free Growth of Monocrystalline Silver Nanosheets: Synergistic Effects of Interfacial Confinement and Oxidative Etching in Plasma-Liquid Systems

Plasma Physics / Physique des plasmas (DPP)

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

The development of sustainable, "green" synthesis routes for two-dimensional (2D) noble metal nanostructures remains a significant challenge in materials science, often requiring complex surfactants, capping agents, or physical templates to induce anisotropy. In this work, we demonstrate a versatile, eco-friendly platform for the precision synthesis of high-aspect-ratio silver (Ag)...
