Elemental Tellurium, Selenium, and Sulfur Nanomaterials for Infrared Optoelectronics and Chiral Physics
This research community focuses on the synthesis and physical properties of elemental chalcogen nanomaterials, primarily tellurium and selenium, to develop infrared photodetectors, field-effect transistors, and chiral electronic devices.
The work centers on growing tellurium in various forms, including nanowires, thin films, and two-dimensional sheets, alongside selenium and sulfur compounds. Recurring themes include the fabrication of chiral crystals and nanostructures, the study of nonlinear optical effects, and the development of acousto-optic tunable filters. Applications span infrared imaging, polarization-sensitive sensing, and neuromodulation. The research also explores the electronic properties of these materials, such as the bulk photovoltaic effect and charge-to-spin conversion, often in the context of room-temperature operation and integration with silicon or other substrates.
The community is most heavily concentrated in tellurium research, accounting for 3.1% of all tellurium papers, and selenium research, representing 1.5% of all selenium papers. Tellurium also contributes the highest number of papers to this group, with 2,032 entries.
There are 6,358 papers in this community, with the most frequent publications appearing in the Journal of Non-Crystalline Solids, physica status solidi (b), and Physical Review B.
Recent work includes the ultrafast growth of millimeter-scale tellurium nanowires, the synthesis of wafer-scale oriented tellurium films, and the observation of nonlinear chiral thermoelectric effects in tellurium.
