Oxide Transistors for Neuromorphic Computing: From Defect Physics to Synaptic Array

Taikyu Kim, Yong Jun Jeong, He Young Kang, Jae Kyeong Jeong

ABSTRACT Data‐intensive workloads demand energy‐efficient platforms that seamlessly integrate memory, processing, and spatiotemporal responses. Oxide transistors offer a compelling route toward this goal due to their low‐temperature processability, large‐area uniformity, low off‐state leakage, and defect‐mediated temporal dynamics. In this review, we discuss …

Massively multiplexed microfluidics maps combinatorial and sequential antibiotic responses in 3D

Yong Jun Jeong, Gabriel Mercado-Vasquez, Abinash Padhi, J. Matthews et autres

Current microbial culture and antibiotic susceptibility testing platforms lack dynamic chemical control and do not scale to high-throughput 3D culture. We present an automated microfluidic system that creates 512 independently programmable 3D hydrogel-culture chambers and delivers each chamber a distinct combinatorial and …

Improvement in Performance and Stability of PbS QD/IGZO Phototransistors Through the Introduction of Ga2O3 Film for Broadband Sensor Applications

Yong Jun Jeong, Gwang‐Bok Kim, Min Jae Kim, Jinwook Oh et autres

The development of broadband photosensors has become crucial in various fields. Indium–gallium–zinc oxide (IGZO, In:Ga:Zn = 1:1:1) phototransistors with PbS quantum dots (QDs) have shown promising features for such sensors, such as reasonable mobility, low leakage current, good photosensitivity, and low-cost fabrication. …
