Advanced MaterialsPhotodetectors
Organic and perovskite semiconductors for visible, near-infrared and short-wave infrared photodetection.
Organic photodetectors
We study novel organic materials, charge-transporting layers and device architectures for Vis-NIR-SWIR photodetection. Our work investigates spectral responsivity, device noise, transient response and the origins of dark current in broadband and narrowband detection up to 2000 nm.
Perovskite photodetectors
We investigate perovskite bandgap tuning, interfacial layers and device stability under reverse bias for photodetection applications. Our device research includes heterojunctions and two-dimensional perovskite photoconductors.
Origin of Dark Current and Noise
Accurate noise measurements are fundamental to evaluating photodetector performance. We study the relationships between material energetics and dark current. We also aim to perform precise noise characterization using cutting-edge instruments.
