Defect-driven processing of two-dimensional transition metal dichalcogenides
… phenomena relevant to the fabrication of TMD heterostructures, alloys, and nanoporous membranes are presented. This thesis begins with an investigation of the role of substrate temperature in two-step chemical vapor deposition (CVD) growth of MoS₂/WS₂ heterostructures. We demonstrate …

Infrared detectors based on two-dimensional materials and heterostructures
… technologies enabled by 2D materials and their heterostructures. First, we addressed some of the key challenges for reliable synthesis and characterization of 2D materials and functional nanostructures. We developed a new seeding-promoter-assisted chemical vapor deposition approach for the …

High-throughput characterisation and device integration of nanomaterials
… bilayer graphene, MoS2, and MoSe2/WSe2 lateral heterostructures. First, a novel method for nanofabrication is introduced using a lithography-optimised fiducial marker system LithoTag, which is used for the identification of individual InAs nanowires and for automatically designing >200 …

Device Physics of Two-Dimensional Crystalline Materials
… quantum Hall effects in semiconductor heterostructures and superconductivity in cuprates. In both, the 2D electrons are embedded in complex material structures. The discovery of graphene allows for the isolation of 2D electrons in their simplest form, existing merely in a single …

Nanoscale Characterisation of Heterointerfaces in 2D Materials
… 2D materials. We first examine interfaces in 2D lateral heterostructures of monolayer transition metal dichalcogenides (1L-TMDs). Studies on the synthesis of these structures have shown a range of interface widths can occur, which will influence their properties. We show that information about …
