Engineering a Spin‐Orbit Bandgap in Graphene‐Tellurium Heterostructures

Advanced Functional Materials, EarlyView.
Tellurium intercalation in epitaxial graphene on Ir(111) enables the emergence of a spin–orbit‐induced bandgap with energy spin splitting. By combining STM, ARPES, spin‐resolved ARPES, and DFT, two structural phases are identified, both exhibiting tunable electronic doping.

Targets for producing high purity I-123 [PDF]

, 1978
Tellurium powder in improved targets is bombarded with a cyclotron beam to produce Xe-123. Flowing gas streams carry the Xe-123 through one cold trap which removes Xe-123 that subsequently decays to I-123.

Precision Synthesis of a Single Chain Polymorph of a 2D Solid within Single‐Walled Carbon Nanotubes

Advanced Materials, EarlyView.
The precise synthesis of 1D materials has enabled the discovery of physical properties only accessible in length scales close to the atomic scale. Herein, it is demonstrated that encapsulation within single‐walled carbon nanotubes with matching diameters leads to a stoichiometric quasi‐1D van der Waals polymorph of a 2D pnictogen chalcogenide, Sb2Te3 ...

Wafer‐Scale Synthesis of Topological Insulator Sb2Te3 Thin Films

Advanced Materials Interfaces, EarlyView.
This work demonstrates how the topologically protected conduction in Sb2Te3 thin films can be extended from few‐mm2 samples’ area up to larger areas of several cm2 Si(111) wafers. The reported findings represent a breakthrough for the future technology scale‐up of topological insulators for applications such as spintronics, thermoelectrics, and quantum

Chemical Vapor Deposition for the Fabrication of WTe2/h‐BN Heterostructures

Advanced Materials Interfaces, EarlyView.
Chemical vapor deposition (CVD) is studied to produce WTe2 atomic crystals with different morphologies on Si/SiO2 and Si/SiO2/h‐BN substrates. The formation of vertical WTe2/h‐BN heterostructures can be achieved by using a slightly increased temperature as compared to SiO2 substrates, and characterization, including Raman and XPS studies, confirms the ...
