Atomic layer deposition of Zn(O,S) thin films with tunable electrical properties by oxygen annealing
(American Institute of Physics, 2013)Zinc oxysulfide, Zn(O,S), films grown by atomic layer deposition were annealed in oxygen to adjust the carrier concentration. The electron carrier concentration of Zn(O,S) can be reduced by several orders of magnitude from ... -
Exploiting pattern transformation to tune phononic band gaps in a two-dimensional granular crystal
(Acoustical Society of America, 2012)The band structure of a two-dimensional granular crystal composed of silicone rubber and polytetrafluoroethylene (PTFE) cylinders is investigated numerically. This system was previously shown to undergo a pattern ... -
Tunable Nanometer Electrode Gaps by MeV Ion Irradiation
(American Institute of Physics, 2012)We report the use of MeV ion-irradiation-induced plastic deformation of amorphous materials to fabricate electrodes with nanometer-sized gaps. Plastic deformation of the amorphous metal \(\text{Pd}_{80}\text{Si}_{20}\) ...
