Herein, we demonstrate the ability to optically tune mobility of electrically powered Janus particles (JPs) that are half-coated with various zinc oxide ($\mathrm{Zn}\mathrm{O}$) semiconducting layers, i.e., polycrystalline, amorphous, and amorphous a ${\mathrm{Si}\mathrm{O}}_{2}$ passivation layer. The $\mathrm{Zn}\mathrm{O}$ semiconductor photoresponse causes an increase in its electrical con...

In thin film technology, future semiconductor and display products with high performance, high density, large area, and ultra high definition with three-dimensional functionalities require high performance thin film transistors (TFTs) with high stability. Zinc oxynitride, a composite of zinc oxide and zinc nitride, has been conceded as a strong substitute to conventional semiconductor film such...

The production of H(2) in highly excited vibrational and rotational states (v=0-5, J=0-17) from the 157 nm photodissociation of amorphous solid water ice films at 100 K was observed directly using resonance-enhanced multiphoton ionization. Weaker signals from H(2)(v=2,3 and 4) were obtained from 157 nm photolysis of polycrystalline ice, but H(2)(v=0 and 1) populations in this case were below th...

Wide-bandgap perovskite stannates are of interest for the emergent all-oxide transparent electronic devices due to their unparalleled room temperature electron mobility. Considering advantage amorphous material in integrating with non-semiconductor platforms, we herein reported optical and properties prototypical stannate, barium stannate (BaSnO3) thin films, which were deposited at annealed va...

Semiconductor blue laser diode was used for crystallization annealing of amorphous silicon backplane flat panel display. The grain size result crystal can be controlled by beam intensity or scanning speed. poly produced BLDA showed same characteristics as ELA in LTPS. Lateral have been BLDA, its field mobility is three times higher than ELA. A multiple head equipment proposed, which high perfor...

In this year’s Phase II photoelectrochemical hydrogen production research at the University of Hawaii, we have continued our emphasis on developing high-performance multi-junction hydrogen photoelectrodes based on low cost semiconductor and catalyst films. Significant progress was made in the advancement of amorphous silicon/germanium and copper indium gallium diselenide materials for solid-sta...
