Large-area, low-voltage, anti-ambipolar heterojunctions from solution-processed semiconductors
Deep Jariwala, Vinod K. Sangwan, Jung-Woo Ted Seo +6
The emergence of semiconducting materials with inert or dangling bond-free surfaces has created opportunities to form van der Waals heterostructures without the constraints of trad…
Effective Passivation of Exfoliated Black Phosphorus Transistors against Ambient Degradation
Joshua D. Wood, Spencer A. Wells, Deep Jariwala +7
Unencapsulated, exfoliated black phosphorus (BP) flakes are found to chemically degrade upon exposure to ambient conditions. Atomic force microscopy, electrostatic force microscopy…
Influence of Stoichiometry on the Optical and Electrical Properties of Chemical Vapor Deposition Derived MoS
In Soo Kim, Vinod K. Sangwan, Deep Jariwala +11
Ultrathin transition metal dichalcogenides (TMDCs) of Mo and W show great potential for digital electronics and optoelectronic applications. Whereas early studies were limited to m…
Wafer-scale solution-derived molecular gate dielectrics for low-voltage graphene electronics
Vinod K. Sangwan, Deep Jariwala, Ken Everaerts +6
Graphene field-effect transistors are integrated with solution-processed multilayer hybrid organic-inorganic self-assembled nanodielectrics (SANDs). The resulting devices exhibit l…
Emerging Device Applications for Semiconducting Two-Dimensional Transition Metal Dichalcogenides
Deep Jariwala, Vinod K. Sangwan, Lincoln J. Lauhon +2
With advances in exfoliation and synthetic techniques, atomically thin films of semiconducting transition metal dichalcogenides have recently been isolated and characterized. Their…
Carbon nanomaterials for electronics, optoelectronics, photovoltaics, and sensing
Deep Jariwala, Vinod K. Sangwan, Lincoln J. Lauhon +2
In the last three decades, zero-dimensional, one-dimensional, and two-dimensional carbon nanomaterials (i.e., fullerenes, carbon nanotubes, and graphene, respectively) have attract…
