描述

應用

• Facile sonochemical synthesis of tellurium and tellurium dioxide nanoparticles: This study presents a method for synthesizing tellurium nanostructures by reducing TeCl4 to Te using ultrasonic irradiation in methanol, also exploring the oxidation process to produce tellurium dioxide (Arab, Mousavi-Kamazani, 2017).


• Ultrathin tellurium dioxide: emerging direct bandgap semiconductor: This article discusses the properties of monolayer tellurium dioxide as a new 2D semiconducting oxide, highlighting its direct bandgap and high mobility, which are significant for various applications (Guo et al., 2018).
