| Abstract | Heavy transition-metal oxides are widely studied for key applications in electronics and energy technologies. In cutting-edge organic-light-emitting-diode (OLED) devices, there remain scientific challenges to achieve an efficient transfer of charges between electrodes and the organic layer. Recently, polymorphic MoO3 has been actively investigated to exploit its unique high work-function values, especially for its use in the electrode buffer layer to effectively transfer the charges in OLED devices. However, no systematic fundamental studies of its electronic structure are available. Thus, in this study, we use first-principles density-functional theory to investigate both the crystal structure and the electronic structure of the MoO3 polymorphs, and we conclude with a simple perspective to screen the best candidate for OLED applications via a hole transport-barrier descriptor. |
