Directed Assembly of One-Dimensional Nanostructures into Functional Networks
One-dimensional nanostructures, such as nanowires and nanotubes, represent the smallest dimension for efficient transport of electrons and excitons and thus are ideal building b...
Charge-density waves and superlattices in the metallic layered transition metal dichalcogenides
Abstract The d1 layer metals TaS2, TaSe2, NbSe2, in all their various polytypic modifications, acquire, below some appropriate temperature, phase conditions that their electroma...
Microfluidic Large-Scale Integration
We developed high-density microfluidic chips that contain plumbing networks with thousands of micromechanical valves and hundreds of individually addressable chambers. These flu...
Recent advances and applications of machine learning in solid-state materials science
Abstract One of the most exciting tools that have entered the material science toolbox in recent years is machine learning. This collection of statistical methods has already pr...
Hydrogen as a Cause of Doping in Zinc Oxide
Zinc oxide, a wide-band-gap semiconductor with many technological applications, typically exhibits n-type conductivity. The cause of this conductivity has been widely debated. A...
