Field-effect transistors made of individual colloidal PbS nanosheets
Sedat Dogan, Thomas Bielewicz, Yuxue Cai +1
Two-dimensional materials are considered for future quantum devices and are usually produced by extensive methods like molecular beam epitaxy. We report on the fabrication of field…
Metal nanoparticle field-effect transistor
Yuxue Cai, Jan Michels, Julien Bachmann +1
We demonstrate that by means of a local top-gate current oscillations can be observed in extended, monolayered films assembled from monodisperse metal nanocrystals -- realizing tra…
Tunable electrical transport through annealed monolayers of monodisperse cobalt-platinum nanoparticles
Yuxue Cai, Denis Wolfkuhler, Anton Myalitsin +3
We synthesized monodisperse cobalt-platinum nanoparticles Co(0.14-0.22)Pt(0.86-0.78) of 9 nm in diameter by colloidal chemistry methods and deposited them by the Langmuir-Blodgett…
Growth and reductive transformation of a gold shell around pyramidal cadmium selenide nanocrystals
Michaela Meyns, Neus G. Bastus, Yuxue Cai +4
We report the growth of an unstable shell-like gold structure around dihexagonal pyramidal CdSe nanocrystals in organic solution and the structural transformation to spherical doma…
Carbon supported CdSe nanocrystals
Beatriz H. Juarez, Michaela Meyns, Alina Chanaewa +3
Insights to the mechanism of CdSe nanoparticle attachment to carbon nanotubes following the hot injection method are discussed. It was observed that the presence of water improves…
