Hierarchical PbTe/PbSe materials with both well-defined primary microstructures and well-ordered secondary nanostructures have been fabricated via a facile solvothermal method. The crystallinity,...

2005年1月1日 · Hagström and Fahlman [14] performed a comparative study of the interaction of oxygen with PbTe and PbS (1 0 0) surfaces by means of UPS and XPS. They found that PbS surface is hardly oxidised even at 10 12 L exposures, whereas for PbTe the oxidation starts at ca. 10 7 L exposures and includes two steps, as described above.

XPS Spectra Tellurium (Te) Compounds The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra.

2025年1月21日 · In this manuscript, we present a modified hot-injection synthesis method that combines OA with shorter carboxylic acids (OctA, DA, and LA) to tune PbTe QD size and morphology across a range of...

2025年2月5日 · First-principles calculations and X-ray photoelectron spectroscopy results indicate that PbTe-doped LBE aerosols should preferentially generate TeO 2 during the interaction with oxygen. This work provide a reasonable prediction method for the migration characteristics of polonium under severe accident. 1. Introduction.

2016年12月22日 · We report the determination of band alignment of PbTe/SnTe (111) heterojunction interfaces using X-ray photoelectron spectroscopy (XPS). Multiple core levels of Pb and Sn were utilized to determine the valence band offset (VBO) of the heterojunction.

2016年11月1日 · 我们报告了使用 X 射线光电子能谱 (XPS) 确定 PbTe/SnTe (111) 异质结界面的能带排列。 利用 Pb 和 Sn 的多个核心水平来确定异质结的价带偏移 (VBO)。 XPS 结果显示 III 型能带对准，VBO 和导带偏移 (CBO) 。

2002年8月1日 · The effect of several chemical and physical treatments for PbTe(100) surface cleaning was investigated by XPS. Etching with a (NH4OH+H2O2) solution shows a remarkable contrast to etching with acid, …

Hagstro ̈m and Fahlman [14] performed a comparative study of the interaction of oxygen with PbTe and PbS(100) surfaces by means of UPS and XPS. They found that PbS surface is hardly oxidised even at 1012L exposures, whereas for PbTe the oxi-dation starts at ca. 107L exposures and includes two steps, as described above.

在几分钟到几个月的时间范围内，通过 XPS 研究了 (Pb,Ge)Te 晶体表面在环境温度和湿度下的氧化。 真空裂解晶体用于实验。 发现 PbTe 晶格中的 Ge 占据两个不同的位置。
