Different healing characteristics of thiol-bearing molecules on CVD-grown MoS<sub>2</sub>

چکیده

Abstract Vacancies in atomically thin molybdenum disulfide play an essential role controlling its optical and electronic properties, which are crucial for applications sensorics, catalysis or electronics. For this reason, defect engineering employing thiol-terminated molecules is used to heal and/or functionalise defective nanosheets. In work, CVD-grown MoS 2 with different densities was functionalised three molecules: 4-aminothiophenol (ATP), biphenyl-4-thiol (BPT) 4-nitrothiophenol (NTP). The molecules’ efficacy functionalising probed by X-ray photoelectron, Raman photoluminescence spectroscopy. results show that exposing a single layer of either ATP, BPT NTP heals the defects, however chemical structure these affects response only intensity increases.

Nanoelectronic biosensors based on CVD grown graphene.

Graphene, a single-atom-thick and two-dimensional carbon material, has attracted great attention recently. Because of its unique electrical, physical, and optical properties, graphene has great potential to be a novel alternative to carbon nanotubes in biosensing. We demonstrate the use of large-sized CVD grown graphene films configured as field-effect transistors for real-time biomolecular sen...

Transport Studies on CVD - Grown Graphene

In this thesis, we report transport studies performed on CVD-grown graphene. We perform resistivity and hall measurements on a large-area sample at 4' K. We measure the carrier mobility of the sample and find it to be on the order of 1000 cm 2/Vs, whereas monolayer graphene regularly exhibits much higher mobilities. We also examine what we find to be weak signatures of Shubnikov-de Haas oscilla...

Analysis of the interface characteristics of CVD-grown monolayer MoS2 by noise measurements.

We investigated the current-voltage and noise characteristics of two-dimensional (2D) monolayer molybdenum disulfide (MoS2) synthesized by chemical vapor deposition (CVD). A large number of trap states were produced during the CVD process of synthesizing MoS2, resulting in a disordered monolayer MoS2 system. The interface trap density between CVD-grown MoS2 and silicon dioxide was extracted fro...

Infrared Photodetectors Grown by Rapid Thermal Cvd

GeSii infrared detectors grown by Rapid Thermal CVD are demonstrated. External quantum efficiency of7% at A=1.32jtm and eye-diagram at 1.5Gbit/s are obtained for Ge2Si71 waveguide pin detectors. It is shown that external quantum efficiency is limited by the fiber to waveguide coupling efficiency. These, along with system considerations suggest that with further improvements, such devices can be...
