Vibrational Properties of a Naturally Occurring Semiconducting van der Waals heterostructure
V. Z. Costa, Liangbo Liang, Sam Vaziri +3
We present vibrational properties of Franckeite, which is a naturally occurring van der Waals heterostructure consisting of two different semiconducting layers. Franckeite is a com…
Chemical vapor deposited graphene: From synthesis to applications
Satender Kataria, Stefan Wagner, Jasper Ruhkopf +7
Graphene is a material with enormous potential for numerous applications. Therefore, significant efforts are dedicated to large-scale graphene production using a chemical vapor dep…
Ultrahigh Doping of Graphene Using Flame-Deposited MoO3
Sam Vaziri, Victoria Chen, Lili Cai +5
The expected high performance of graphene-based electronics is often hindered by lack of adequate doping, which causes low carrier density and large sheet resistance. Many reported…
Uncovering the Effects of Metal Contacts on Monolayer MoS2
Kirstin Schauble, Dante Zakhidov, Eilam Yalon +11
Metal contacts are a key limiter to the electronic performance of two-dimensional (2D) semiconductor devices. Here we present a comprehensive study of contact interfaces between se…
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…
