Mar 16, 2014 · Here, we demonstrate that these states can be enhanced or destroyed by strain in the vicinity of grain boundaries on the surface of epitaxial Bi2Se3(0001) thin films.

Jan 16, 2023 · We show that amorphous Bi 2 Se 3 thin films host a number of two-dimensional surface conduction channels. Our angle-resolved photoemission spectroscopy data are consistent with a dispersive...

Dec 25, 2021 · In this manuscript, a review on the meticulous studies of Bi2 Se 3 is presented where different synthesis techniques; crystal structures; various physical properties and modern day applications were taken into concern. 1. Introduction to topological insulator.

TEM and FE-SEM analysis suggest formed Bi2Se3 NPs shell has been uniformly decorated onto the surface of CdS NWs core leading to enhanced light absorption by shifting the absorption edge towards...

Nov 1, 2004 · TEM and HRTEM observation indicate that the nanoflakes synthesized at 150–210 °C are 50–500 nm in width, and 2–5 nm in thickness, and the size and thickness of the nanoflakes increase with increase heating temperature.

Morphologies and good crystallinity of the synthesized samples have been verified by the TEM images, high resolution TEM (HRTEM) images, and SAED patterns, as shown in Figure 3.

Mar 1, 2025 · In this paper, we present a novel Bi 2 Se 3 synthesis process using a combination of two different processes that result in low cost, large-area scalability, and ease of patterning for improved productivity.

Transmission electron microscopy (TEM) images, selected-area electron diffraction (SAED) patterns, and energy dispersive X-ray spectroscopy (EDS) spectrum were obtained from FEI Tecnai F30 apparatus operated at an accelerating voltage of 300 kV with a point-to-point resolution of 2Å.

Bismuth selenide (Bi2Se3) and nickel (Ni) doped Bi2Se3 were prepared by a solvothermal approach to explore the photo-catalytic performance of the materials in degradation of malachite green...

Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) have been carried out to clarify the microstructure of Bi 2 Se 3 thin films grown by molecular beam epitaxy (MBE) on Si (111) and InP (111) substrates.
