Two-Dimensional materials: from large-area growth to the performance in radio-frequency range

This thesis presents a collection of experimental results about the large-area growth of single-layer graphene and MoS2 films. In addition, we present the results of electrical characterisation of two-dimensional (2D) materials in direct current (DC) and r ...

Vacuum ultraviolet excitation luminescence spectroscopy of few-layered MoS2

Andras Kis, Daria Krasnozhon, Wei Cao

We report on vacuum ultraviolet (VUV) excited photoluminescence (PL) spectra emitted from a chemical vapor deposited MoS2 few-layered film. The excitation spectrum was recorded by monitoring intensities of PL spectra at similar to 1.9 eV. A strong wide exc ...

MoS2 Transistors Operating at Gigahertz Frequencies

Andras Kis, Yusuf Leblebici, Clemens Benedict Nyffeler, Dominik Sebastian Lembke, Daria Krasnozhon

The presence of a direct band gap1-4 and an ultrathin form factor5 has caused a considerable interest in two-dimensional (2D) semiconductors from the transition metal dichalcogenides (TMD) family with molybdenum disulfide (MoS2) being the most studied repr ...
