Bond and electronic relaxation dynamics of graphene, gold clusters, and water ice
Published 2013“…Consistency between the BOLS-TB calculation and density functional theory (DFT) calculation on graphene nanoribbons (GNRs) verified that i) the physical origin of the band gap expansion lays in the enhancement of edge potentials and hopping integrals due to the shorter and stronger bonds between undercoordinated atoms; and ii) nonbond electrons at the edge of zigzag-edged GNRs and atomic vacancies accompanied with the broken bond contribute to the Dirac-Fermi polaron (DFP) with a local magnetic momentum; iii) the formation of triple bond at the edge of armchair-edged and reconstruct-edged GNRs annihilates the nonbond electron and prevent formation of DFPs. …”

Interface engineering for organic−inorganic hybrid perovskite solar cells
Published 2022“…Specifically, modifications were conducted to the electron transport layer (ETL), as well as the ETL/ OIHP and OIHP/ hole transport layer (HTL) interfaces. Hence, this thesis hopes to encourage the commercialization of OIHP solar cells by using premediated passivation materials at various interfaces for the creation of highly efficient, reliable, and stable of OIHP solar cells. …”

P4-network : a networking infrastructure for intra-aircraft cabin wireless communication
Published 2009“…In particular, a pinging test over a path of four hops takes less than a hundred millise-conds. As a primitive but fundamental result, this work has shown different promising aspects of the proposed solution on a limited hardware platform, including stability, availability, scalability and high performance. …”

Optimization and scheduling for a large-scale urban transportation system involving human factors
Published 2020“…The thesis includes three technical chapters: The first technical chapter develops a model to provide traffic light scheduling for pedestrian-vehicle mixed-flow networks, where a macroscopic pedestrian "hopping" model at an intersection is formulated, which is capable of reflecting the changing capacity during one time interval resulted from the crosswalk length and pedestrian relatively lower speed. …”

Carbon-semiconductor hybrid nanostructures and their photoresponse behaviors
Published 2013“…According to the understanding on electrons transport in nanoparticle structures, under illumination, the photogenerated electrons repeatedly interact with a distribution of traps as they undertake a random hopping through the nanoparticles. A photogenerated electron may experience a million trapping events before being collected by electrode." …”
