Graphene nanoribbons

July 21, 2022 Manufacturing, Nanotech Comments Off on Graphene nanoribbons

Graphene is a 1-atom-thick layer of tightly bonded carbon atoms arranged in a hexagonal lattice. Graphene the world’s first 2D nanomaterial, is widely regarded as the “wonder material” of the 21st century due to the combination of its extraordinary properties. As a single layer of graphite, it is the thinnest …

Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation. There is a wide variety of photodetectors that may be classified by mechanism of detection, such as photoelectric or photochemical effects, or by various performance metrics, such as spectral response. Photodetectors are devices that measure photon flux or …

Dynamic metasurfaces including Liquid crystal metasurfaces allow tuning of metasurface functionality also after fabrication.

June 15, 2022 Nanotech, Photonics Comments Off on Dynamic metasurfaces including Liquid crystal metasurfaces allow tuning of metasurface functionality also after fabrication.

Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. This class of micro- and nano-structured artificial media are predicted to be able to protect …

Molecular spintronics is emerging field of nanoscale electronics that uses molecules to build ultrafast, low power electronics devices

May 23, 2022 Electronics & EW, Nanotech Comments Off on Molecular spintronics is emerging field of nanoscale electronics that uses molecules to build ultrafast, low power electronics devices

The age of electrically-based devices has been with us for more than six decades.

Nano-opto-electro-mechanical systems (NOEMS)

April 23, 2022 Mechanical, Nanotech, Photonics Comments Off on Nano-opto-electro-mechanical systems (NOEMS)

Modern microelectronic semiconductors and integrated circuits provide remarkable computational and memory capabilities but lack the capability to interface with the physical world directly. MEMS (MicroElectroMechanical Systems) and the even smaller NEMS (Nano ElectroMechanical Systems) integrate sensors and actuators on microelectronic circuitry and enabling these products, awareness of the surroundings in …

Carbon Nanotubes assembly, manufacturing integration processes usher carbon revolution for post silicon future

April 17, 2022 Manufacturing, Nanotech Comments Off on Carbon Nanotubes assembly, manufacturing integration processes usher carbon revolution for post silicon future

Carbon nanotubes (CNTs) are hollow cylindrical tubes formed by rolling a sheet of carbon atoms arranged in a hexagonal ring, as in a sheet of graphite, either in monolayer (single-walled nanotube, SWCNT) or multilayer (multi-walled nanotube, MWCNT) form. CNTs exhibit different electronic properties based on the way these graphene …
