The term Memtransistor, a portmanteau of memristor and transistor, (and no relation to MEMS transistors), is generally used to describe a class of proposed and experimental hybrid memristor-transistors. In general it refers to multi terminal (two-terminal and greater) hybrid memristor-transistive devices and models which attempt to exhibit memristive switching effects. Models primarily look to leverage […]
Researchers out of Korea recently published a paper on their success in implementing a single titanium oxide based memristor integrated with a single crystal silicon transistor. In addition to future research into improvements for the “read” problem of nonvolatile memory via a diode and unipolar resistor combination, they created and tested a 1 Transistor, 1 […]
Graphene continues to show its potential with a new paper out detailing the production of 40nm graphene transistors (on diamond carbon substrate) that scaled to cut off frequencies up to 155Ghz, researchers out of IBM’s Thomas J. Watson Research Center, New York stated: The CVD [chemical vapour deposition] graphene was grown on copper film and […]
Thermoelectric peltier cooling effects at graphene and metal junctions have been demonstrated by a group out of the University of Illinois. Kyle Grosse, Feifei Lian, Myung-Ho Bae,William King, and Eric Pop used “… atomic force microscopy to measure the temperature distributions at the contacts of working graphene transistors”: Our data indicate that thermoelectric effects account […]
Things are heating up in the nanoscale programmable logic circuit “circuit”… A paper submitted to Nature last August has been published this month detailing further advances into the “transputer” programmable logic grail, this time fabricated utilizing ge/si based FET nanowires. The researchers were able to reprogram a so constructed logic tile and implement multiplexer, demultiplexer, […]
A new paper in Nature: Nanotechnology titled “Spectroscopy of few-electron single-crystal silicon quantum dots” shows the result of a 4nm fabrication utilizing phosphorous/silicon replacement in modeling a seven atom transistor: “The quantum dot is defined by atomically abrupt changes in the density of phosphorus dopant atoms, and the resulting confinement produces novel effects associated with […]
Emerging technology provides a unique opportunity to introduce science within education. The development of Memristors, the fourth passive component type after resistors, capacitors and inductors, along with other Solid State memory devices, takes us one step further to creating cheap, powerful, distributed solutions for sensing and processing.
