Some aspects of Metalenz and microchip fabrication of nanoscale deices.
The Nanotechnology Revolution Is Here—We Just Haven't Noticed Yet
The Wall Street Journal, Christopher Mims, January 22, 2022
The nanotechnology revolution is quietly underway, with scientists harnessing microchip fabrication technology to create nanoscale devices. For example, Resonant makes microelectromechanical systems incorporated into smartphones to filter radio interference via vibrating elements. Another nanomachine, the metalens, a thin and virtually flat lens covered with thousands of silicon fibers, can bend light in ways that used to require multiple conventional lenses; applications include three-dimensional (3D) smartphone sensors, which metalens maker Metalenz will produce with semiconductor manufacturer STMicroelectronics. Meanwhile, the Georgia Institute of Technology's Andrei Fedorov and colleagues used electron beams to etch patterns in two-dimensional materials, or to stack structures made of carbon atoms atop them.
