recommendations! Published in 2024 at "European Journal of Inorganic Chemistry"

DOI: 10.1002/ejic.202400762

Abstract: Chemical vapor deposition using molecular compounds is a salient method to achieve high‐quality, uniform films comprising two‐dimensional flakes. In this communication, we present the synthesis and characterization of analytically pure single crystals of Bi[Se‐(2‐Me2NC6H4)]3, used… read more here.

DOI: 10.1063/1.5054806

Abstract: We investigated spin-to-charge current conversion in sputtered Y3Fe5O12 (YIG)/granular bismuth selenide (GBS) bi-layers at room temperature. The spin current is pumped to the GBS layer by the precession of magnetization at ferromagnetic resonance in the… read more here.

DOI: 10.1088/1361-6439/ac1453

Abstract: We demonstrate memristive functions of the room temperature thermoelectric material Bi-Se fabricated by electrochemical deposition in combination with active electrode Ag-based contacts. We present microfabrication steps for creating polymer molds for the growth of compact… read more here.

DOI: 10.1088/1402-4896/adedd0

Abstract: Surface Plasmon Resonance (SPR) biosensors are attractive for refractive index (RI) sensing, but existing designs often suffer from limitations in sensitivity, tunability, and fabrication complexity. To address these challenges, we propose a novel Metal-Insulator-Metal (MIM)… read more here.

DOI: 10.1126/sciadv.aar7214

Abstract: Bismuth selenide becomes superconducting upon coupling to metallic niobium, and its topological states pair up to form a gap. A topological insulator film coupled to a simple isotropic s-wave superconductor substrate can foster helical pairing… read more here.

DOI: 10.3390/nano15010052

Abstract: As an emerging two-dimensional (2D) Group-VA material, bismuth selenide (Bi2Se3) exhibits favorable electrical and optical properties. Here, three distinct morphologies of Bi2Se3 were obtained from bulk Bi2Se3 through electrochemical intercalation exfoliation. And the morphologies of… read more here.
