Tellurium nanostructures for optoelectronic applications

Reduced graphene oxide doped tellurium nanotubes for high performance supercapacitor

“…Figure 1C displays the FTIR spectra of rGO, Te, and TG 1 to TG5 samples. The band molecular environment of synthesized Te-tube was well explained in our previous report (Rani et al, 2022). For Te, the peak appeared at 667 cm −1 is the primary interest that belongs to Te-O bonds (Trivedi et al, 2015).…”

“…The synthesis of Te-tubes has been carried out using a facile wet chemical method reported previously ( Rani et al, 2022 ). Firstly, 10 mmol of sodium telluride and sodium molybdate were added in hydrazine hydrate and deionized distilled water (in ratio 1:3) solution.…”

Thermophysical Assessments on Self-Assembled Tellurium Nanostructures

“…These properties make them attractive for a number of applications, which include the medical field, imaging, catalysis, environmental remediation, and the energy sector. , Furthermore, tellurium (Te) has attracted the attention of many researchers and manufacturers. Te is one of the heaviest, nonradioactive members of the chalcogen family, which is a p-type semiconductor with a very narrow bandgap energy of ∼0.35 eV at room temperature. , Discovered in the seventeenth century by Franz-Joseph Muller von Reichenstein, the abundance of Te is only one part per billion compared with the other rare elements like gold and platinum . Te exhibits intriguing and exciting properties including nonlinear optical responses and photo-conductivity, photo-electricity, piezo-electricity, catalytic activity, and biomedical properties.…”

“…However, studies on structural phase transition and surface/interface-dependent thermal properties have not been analyzed and reported thus far. In our previous communication, Rani et al studied the optoelectronic aspects of the tellurium nanostructures (TeN). In this, they observed structure-dependent optical phenomena.…”

“…Herein, we investigated the structural phase transitions that had occurred during the growth of TeN. TeN were synthesized using a simple wet-chemical technique under the specific thermodynamic conditions reported in ref . The system exhibited a sharp phase change from 1D tube to 2D flake at a particular reaction time (6 h, i.e., 0.85 t N ).…”
