Latest Patents

One of Hong-Sub Lee's latest patents is titled "Method for fabricating a memtransistor." This invention involves a method for creating a memtransistor by growing a polycrystalline monolayer film on a substrate. The film contains grains that define a plurality of grain boundaries. An electrode array is then formed on the polycrystalline monolayer film, with electrodes electrically coupled to the film, allowing each pair of electrodes to define a channel within it.

Another significant patent is "Multi-terminal memtransistors and applications of the same." This invention describes a multi-terminal memtransistor that includes a substrate with a first and second surface. A polycrystalline monolayer film made of an atomically thin material is formed on the first surface. An electrode array is spatially formed on the film, with each pair of electrodes defining a channel. Additionally, a gate electrode is placed on the second surface, capacitively coupled with the channel. This multi-terminal memtransistor operates similarly to a neuron, performing both memory and information processing, making it a foundational element for new forms of neuromorphic computing.
