Li, QiliangYu, Sheng2017-01-292017-01-292016https://hdl.handle.net/1920/10619Two-dimensional (2D) layered materials, such as hexagonal boron nitride (h-BN) and transition metal dichalcogenides (TMDCs), have gained considerable attentions for electronic applications. Their mechanical properties, possible application in body movement, muscle stretching and blood vessel contraction, have also been studied. The MoS2 monolayer, a typical member of 2D TMDCs, becomes piezoelectric after exfoliation from the bulk crystal whereas the inversion symmetry is broken. Therefore, MoS2 nanostructures have become promising in NEMS application in nanopiezotronics, a rapidly emerging field.108 pagesenCopyright 2016 Sheng YuElectrical engineering2D materialsDirac FermionsMechano-Electric ConverterStrain EffectDissertation
