Emulating Bilingual Synaptic Response Using a Junction-Based Artificial Synaptic Device

ACS Nano, 2017
Excitatory and inhibitory postsynaptic potentials are the two fundamental categories of synaptic responses underlying the diverse functionalities of the mammalian nervous system. Recent advances in neuroscience have revealed the co-release of both glutamate and GABA neurotransmitters from a single axon terminal in neurons at the ventral tegmental area ...

Chalcogenide-Based Artificial Intelligence Synaptic Device

2018 14th IEEE International Conference on Solid-State and Integrated Circuit Technology (ICSICT), 2018
In this work, we investigated sputtered undoped and N-doped Sb 2 Te 3 chalcogenide phase change films by x-ray diffraction and resistance measurements. The application to artificial intelligence synaptic device is presented as well. Mean crystal size decreased from 6.8 to 2.9 nm and thus crystal growth was significantly suppressed by fine nitrides due
