Artificial Optoelectronic Synapse Featuring Bidirectional Post‐Synaptic Current for Compact and Energy‐Efficient Neural Hardware

Hogeun Ahn, Yena Kim, Seunghwan Seo, Jun‐Seo Lee et autres

Abstract Conventional hardware neural networks (HW‐NNs) have relied on unidirectional current flow of artificial synapses, necessitating a differential pair of the synapses for weight core implementation. Here, an artificial optoelectronic synapse capable of bidirectional post‐synaptic current ( I PSC ) is presented, …

Generation and manipulation of isotropic droplets in nematic medium using switchable dielectrophoresis

Bomi Lee, Jun‐Seo Lee, Hyun‐Jin Yoon, Seung‐Ho Hong et autres

Dielectrophoresis (DEP) in a medium with anisotropic dielectric susceptibility is very different from typical DEP in an isotropic medium: The direction of particle actuation can be switched depending on the direction of the susceptibility tensor of the medium. However, the understanding of …
