High-Throughput Multifunctional Materials Characterization With Real-Time Analytics And Feedback, Eric Muckley
Doctoral Dissertations
Novel functional materials are enabling transformational breakthroughs in energy, electronics, manufacturing and medicine. Development of new materials is being fueled by advances in high-performance computing, robotics, and high-throughput methods for materials synthesis and processing. To close the feedback loop between materials design, synthesis and functionality, novel materials must be rapidly screened for stability and functionality under a broad range of ambient environmental conditions. We developed an automated system for simultaneous probing of electrical, optical, gravimetric, and viscoelastic properties of materials under controlled environments, enabling characterization of material response to temperature, pressure, humidity, light intensity, and ambient gas/vapor composition. Control of …
Oxidative And Adsorbent Impacts On Selenide Based Transition Metal Dichalcogenides, Anna Hoffman
Oxidative And Adsorbent Impacts On Selenide Based Transition Metal Dichalcogenides, Anna Hoffman
Doctoral Dissertations
This paper covers an overview of the transition metal dichalcogenides, TMD, class of materials. Their layered van der Waals chemical structure and unique electrical and optical properties, such as an indirect in the bulk to direct band gap in the monolayer transition, has brought research focus to their potential role in nanoelectronics. This paper goes over general TMD properties then focuses on WSe₂. While TMDs posses useful and promising characteristics in their pristine state, without precise control over electrical behavior real world application will never occur. Defect engineering is discussed as a method to tune TMD properties, specifically the effects …

Thermal Conductivity Of Mxy₃ Magnetic Layered Trichalcogenides, Amanda Haglund
Doctoral Dissertations
Moore's Law, stating that the number of transistors that can fit on an integrated circuit should double every two years, stood strong for more than 50 years, but is now rapidly reaching its limits. In order to keep up with the need for ever-increasing computer power, focus is shifting towards new materials and technologies. Following the discovery of stable, atomically-thin graphene sheets in 2004, many materials composed of layered sheets have been (re)discovered with great potential to become the "new silicon", including hexagonal boron nitride (h-BN), metal halides such as RuCl₃, or metal chalcogenides MoS₂ and CrGeTe₃. With the variety …
