Electron Transport across Vertical Silicon / MoS / Graphene Heterostructures: Towards Efficient Emitter Diodes for Graphene-Base Hot Electron Transistors
Melkamu Belete, Olof Engström, Sam Vaziri +4
Heterostructures comprising of silicon (Si), molybdenum disulfide (MoS) and graphene are investigated with respect to the vertical current conduction mechanism. The measured…
Nonvolatile Resistive Switching in Nanocrystalline Molybdenum Disulfide with Ion-Based Plasticity
Melkamu Belete, Satender Kataria, Aykut Turfanda +4
Non-volatile resistive switching is demonstrated in memristors with nanocrystalline molybdenum disulfide (MoS) as the active material. The vertical heterostructures consist of…
Gate-tunable graphene-based Hall sensors on flexible substrates with increased sensitivity
Burkay Uzlu, Zhenxing Wang, Sebastian Lukas +3
We demonstrate a novel concept for operating graphene-based Hall sensors using an alternating current (AC) modulated gate voltage, which provides three important advantages compare…
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…
Monolithically Integrated Perovskite Semiconductor Lasers on Silicon Photonic Chips by Scalable Top-Down Fabrication
Piotr J Cegielski, Anna Lena Giesecke, Stefanie Neutzner +11
Metal-halide perovskites are promising lasing materials for realization of monolithically integrated laser sources, the key components of silicon photonic integrated circuits (PICs…
PtSe2 grown directly on polymer foil for use as a robust piezoresistive sensor
Conor S. Boland, Cormac Ó Coileáin, Stefan Wagner +5
Robust strain gauges are fabricated by growing PtSe2 layers directly on top of flexible polyimide foils. These PtSe2 layers are grown by low-temperature, thermally-assisted convers…
