Defect-Engineered Two-Dimensional Transition Metal Dichalcogenides for High-Efficient Piezoelectric Sensor

Description: Piezoelectricity in two-dimensional (2D) transition metal dichalcogenides (TMDs) has attracted significant attention due to their unique crystal structure and the lack of inversion centers when the bulk TMDs thin down to monolayer. Although the piezoelectricity effect in atomic-thickness TMDs has been demonstrated, they are not scalable. Herein, we demonstrate a piezoelectric effect from large-scale, sputtered MoS2 and WS2 using a robust defect-engineering based on the thermal-solvent annealing… more

Procurement of Smart City Technologies: Smart City or Smart Governance?

Description: This dissertation argues that the core of building smart cities is through the procurement and implementation of smart city technologies (SCTs) by either individual (i.e., smart city) or collaborative endeavors (i.e., smart governance). Given that urbanization problems (e.g., air pollution) usually spill over city boundaries, building smart cities as silos may not solve these problems. Therefore, utilizing smart governance in SCT procurement and implementation should be a better approach. Consi… more
