This research proposes a novel opto-ionic transistor integrating NZTO with graphene for multi-modal control of charge transport through optical and ionic gating mechanisms. The device aims to achieve high photoresponsivity, on/off current ratios, and switching speeds suitable for neuromorphic computing applications.
Key findings
NZTO enhances carrier concentration and conductivity while maintaining optical transparency.
Graphene's exceptional carrier mobility and broadband optical absorption complement NZTO properties.
The proposed device architecture features a vertically-stacked heterostructure for photogating and ionic gating effects.
Targets include photoresponsivity exceeding 10^4A/W and on/off current ratios greater than 10^6.
Limitations & open questions
Limited multi-modal control mechanisms in current transparent electronics.
Unexplored opto-ionic coupling in transparent device architectures.
Interface engineering challenges between NZTO and graphene require further investigation.
