Chemical Synapses01:26

Chemical Synapses

8.5K
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Metal-Semiconductor Junctions

1.3K
The contact of metal and semiconductor can lead to the formation of a junction with either Schottky or Ohmic behavior.
Schottky Barriers
Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The...

Electrical Synapses

11.8K
Electrical synapses found in all nervous systems play important and unique roles. In these synapses, the presynaptic and postsynaptic membranes are very close together (3.5 nm) and are actually physically connected by channel proteins forming gap junctions.
Gap junctions allow the current to pass directly from one cell to the next. In contrast, in the chemical synapse, the neurotransmitters carry the information through the synaptic cleft from one neuron to the next. They consist of two...

Neural Circuits01:25

Neural Circuits

3.2K
Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

  • Organic electronics
  • Materials science
  • Neuroscience

Background:

  • Organic ferroelectric transistors are promising for low-cost synaptic devices.
  • Donor-acceptor semiconducting polymers and poly-(vinylidene fluoride) (PVDF) copolymers are key for mimicking synaptic responses.

Purpose of the Study:

  • Synthesize and evaluate novel pyridyl triazole (PyTr) based copolymers for synaptic transistor applications.
  • Investigate the impact of linker units and semiconductor-dielectric interfaces on device performance and neuromorphic functionality.

Main Methods:

  • Three PyTr copolymers with varied linkers (selenium-substituted thiophene, benzothiadiazole, fluorine-substituted thiophene) were synthesized.
  • Transistor architectures using PVDF-HFP dielectric were fabricated to study p-type transport and carrier mobility.
  • Synaptic plasticity was assessed via pulsed gate voltages, and neuromorphic functionality was tested in a multilayer perceptron for image recognition.

Main Results:

  • Carrier mobilities ranged from 0.1 to 0.2 cm2 V-1 s-1.
  • The benzothiadiazole linker copolymer achieved ~80% image recognition accuracy.
  • The fluorine-substituted thiophene linker copolymer exhibited no synaptic behavior, emphasizing interface importance.

  • The choice of linker unit significantly impacts synaptic transistor performance.
  • The semiconductor-dielectric interface properties are critical for successful neuromorphic device operation.
  • Further investigation into interface trap density and morphology is needed to optimize device design.
