2009年5月10日 · First-principles calculations predict that Bi2Se3, Bi2Te3 and Sb2Te3 are topological insulators—three-dimensional semiconductors with unusual surface states generated by spin–orbit coupling ...

2013年2月12日 · In this work, we have synthesized various Bi 2 Se 3 nanocrystals with various morphologies, including nanotower, nanoplate, nanoflake, nanobeam and nanowire, using a simple CVD method. To the...

Bi2Se3主要表现为位于界面Se原子周围的电荷耗尽区域，而电荷积累发生在ZnSe周围。 相应的二维剖面图显示了载流子从Bi2Se3到ZnSe的强烈的自发转移。

2021年12月25日 · 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.

2022年10月1日 · We design a hexagram-like 1D/2D van der Waals heterostructure composed of regularly crosslinked aligned 1D Bi2 S 3 nanowires on 2D Bi 2 Se 3 nanoplates, termed Bi 2 S 3 /Bi 2 Se 3 vdWHs, for use as anode materials for potassium ion batteries (PIBs) and hybrid capacitors (PIHCs).

2021年11月19日 · Herein, we present a comprehensive summary on the recent advances of 2D Bi2 Se 3 materials. The structure and inherent properties of Bi 2 Se 3 are firstly described and its preparation approaches (i.e., solution synthesis and van …

2D layered materials with diverse exciting properties have recently attracted tremendous interest in the scientific community. Layered topological insulator Bi 2 Se 3 comes into the spotlight as an exotic state of quantum matter with insulating bulk states and metallic Dirac-like surface states.

2011年6月24日 · Our results demonstrate that the topological surface state on Bi2Se3 is highly spin polarized and that the dominant factors limiting the polarization are mainly extrinsic. We performed high-resolution spin- and angle-resolved photoemission spectroscopy studies of the electronic structure and the spin texture on the surface of Bi2Se3, a model TI.

6 天之前 · The thermoelectric properties of Bi2Se3 single crystals were investigated with Sb and Te co-doping using a modified vertical Bridgman method, complemented by theoretical studies. X-ray diffraction confirmed the rhombohedral crystal structure with an R $$\\overline{3 }$$ 3 ¯ m space group. High-resolution X-ray diffraction (HR-XRD) analysis revealed a high degree of periodicity, threefold ...

2010年6月13日 · In this work, by combining MBE, angle-resolved photoemission spectroscopy (ARPES) and model calculations, we have systematically studied the thickness-dependent evolution of the band and spin...
