dc.description.abstract | 2D and 1D van der Waals metal chalcogenides (VMC) exhibit unique quantum properties never observed before in classical materials. The growth of continuous 2D large-area film using chemical vapor deposition has been difficult due to the lack of uniform control. For the synthesis of 1D-VMC, it is largely unexplored. In this dissertation, the molecular beam epitaxy of continuous and uniform nanofilms of 2D-MoSe2 and 2D-In2Se3 are studied, in which the former attains high crystallinity and electron mobility of ~15 cm2/Vs in ultrathin field-effect transistor, and the latter is grown using low temperature and exhibits of giant electroresistance ratio of >10^6, which is never observed before in ferroresistive diode junction, for 2D memory application. A new approach in growing 1D-MoSe2 is also investigated, in which the nanoribbon width is highly tunable via the growth parameters. This dissertation presents insights on the MBE of 2D- and 1D-VMC for the advancement of next-generation applications. | |
