Single Crystalline Colloidal Quasi-Two-Dimensional Tin Telluride
Fu Li, Jiecai Fu, Abderrezak Torche +5
Tin telluride is a narrow gap semiconductor with promising properties for IR optical applications and topological insulators. We report a convenient colloidal synthesis of quasi-tw…
Function follows form: From semiconducting to metallic towards superconducting PbS nanowires by faceting the crystal
Mohammad Mehdi Ramin Moayed, Sascha Kull, Angelique Rieckmann +8
In the realm of colloidal nanostructures, with its immense capacity for shape and dimensionality control, the form is undoubtedly a driving factor for the tunability of optical and…
Virtually Bare Nanocrystal Surfaces - Significantly Enhanced Electrical Transport in CuInSe2 and CuIn(1-x)Ga(x)Se2 Thin Films upon Ligand Exchange with Thermally Degradable 1-Ethyl-5-thiotetrazole
Jannika Lauth, Jakob Marbach, Andreas Meyer +4
We present a facile and safe ligand exchange method for readily synthesized CuInSe2 (CIS) and CuIn(1-x)Ga(x)Se2 (CIGS) nanocrystals (NCs) from oleylamine to 1-ethyl-5-thiotetrazole…
CdS nanoparticles capped with 1-substituted 5-thiotetrazoles: Synthesis, characterization, and thermolysis of the surfactant
Sergei V. Voitekhovich, Dmitri V. Talapin, Christian Klinke +2
We propose a new type of surfactants, namely, tetrazole derivatives which can be controllably removed from the nanoparticle surface. Tetrazoles are a peculiar class of heterocyclic…
