Contact Resistance Study of Various Metal Electrodes with CVD Graphene
Amit Gahoi, Stefan Wagner, Andreas Bablich +3
In this study, the contact resistance of various metals to chemical vapour deposited (CVD) monolayer graphene is investigated. Transfer length method (TLM) structures with varying…
Few-Layer MoS/a-Si:H Heterojunction pin-Photodiodes for extended Infrared Detection
Andreas Bablich, Daniel S. Schneider, Paul Kienitz +11
Few-layer molybdenum disulfide (FL-MoS) films have been integrated into amorphous silicon (a-Si:H) pin photodetectors. To achieve this, vertical a-Si:H photodiodes were grown b…
Flexible hybrid graphene/a-Si:H multispectral photodetectors
Daniel S. Schneider, Andreas Bablich, Max C. Lemme
We report on the integration of large area CVD grown single- and bilayer graphene transparent conductive electrodes (TCEs) on amorphous silicon multispectral photodetectors. The br…
Spectral Sensitivity of Graphene/Silicon Heterojunction Photodetectors
Sarah Riazimehr, Andreas Bablich, Daniel Schneider +5
We have studied the optical properties of two-dimensional (2D) Schottky photodiode heterojunctions made of chemical vapor deposited (CVD) graphene on n- and p-type Silicon (Si) sub…
Optimizing the Optical and Electrical Properties of Graphene Ink Thin Films by Laser-annealing
Sepideh Khandan Del, Rainer Bornemann, Andreas Bablich +6
We demonstrate a facile fabrication technique for graphene-based transparent conductive films. Highly flat and uniform graphene films are obtained through the incorporation of an e…
Heterojunction Hybrid Devices from Vapor Phase Grown MoS
Chanyoung Yim, Maria O`Brien, Niall McEvoy +9
We investigate a vertically-stacked hybrid photodiode consisting of a thin n-type molybdenum disulfide (MoS) layer transferred onto p-type silicon. The fabrication is scalabl…
