For example, characterization of charge carrier transport in monolayer graphene as a function of solutal variables is critical for developing sensors capable of characterizing biological fluids. For example, ionized components in an aqueous system can alter the ionic strength and acidity and have strong implications regarding structure-function relationships of biomolecules like proteins and nucleic acids, influencing the efficacy of graphene-based devices for biological assays. Monolayer graphene, a semimetal, can form heterostructures via van der Waals intermolecular forces with other two-dimensional materials like hexagonal boron nitride, a wide-bandgap semiconductor.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>Recently, both monolayer graphene and hexagonal boron nitride have reached wafer-scale commercialization, affording an opportunity to increase throughput for characterization of two-dimensional heterostructures for biosensing applications. Contemporary diagnostics rely on expensive, time-consuming, optically-limited mechanisms that obstructs complete access to biomolecular profiles. Two-dimensional heterostructures may unlock the information needed to profile physiology and disease beyond current state-of-the-art technology.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<div class=\"bu_collapsible_container \" aria-live=\"polite\" data-customize-animation=\"false\"><h4 class=\"bu_collapsible\" aria-expanded=\"false\"tabindex=\"0\" role=\"button\">Research Goals<\/h4><div class=\"bu_collapsible_section\" style=\"display: none;\">\u2022 Fabrication of two-dimensional field-effect transistors<br \/>\n\u2022  Characterization of the two-dimensional field-effect transistors: two- and three-terminal electrical measurements, Raman spectroscopy, optical microscopy<br \/>\n\u2022 Aid in the assembly of a Hall effect measurement station using computer-aided design (Solidworks), programing electrical measurement instrumentation with a computer (matlab), and integration of a fluidics circuit<\/div>\n<\/div>\n\n<div class=\"bu_collapsible_container \" aria-live=\"polite\" data-customize-animation=\"false\"><h4 class=\"bu_collapsible\" aria-expanded=\"false\"tabindex=\"0\" role=\"button\">Learning Goals<\/h4><div class=\"bu_collapsible_section\" style=\"display: none;\">\u2022 Learn about the design and fabrication in cleanroom<br \/>\n\u2022 Learn about graphene device physics<br \/>\n\u2022 Learn how to plan a short-term project and execute<br \/>\n\u2022 Learn interpersonal skills to achieve research and learning goals<\/div>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Wide-and Zero-bandgap Two-dimensional Devices for Liquid\u00a0Sensing\u00a0Applications Project Description \u00a0Two-dimensional materials are atomically thin and readily couple to liquids at a phase interface resulting in perturbation of electrical transport.
