Public Lecture: “How Things Work: The Nano of Computers”

In September 2014, CRISP hosted a public lecture to school children and their parents entitled “How Things Work: The Nano of Computers” by Prof. Sohrab Ismail-Beigi, which described how common electronic devices such as computers and cell phones work. The event also featured hands-on demonstrations for participants that included electronic storage, light emitting devices, deconstructed computer processors, and memory devices.

Using a single atomic layer to turn an insulator into a metal

Kumah, Malashevich, Disa, Arena, Walker, Ismail-Beigi, & Ahn, Phys. Rev. Appl. 2 054004 (2014
By precisely controlling the surface composition of thin oxide films, films can be switched from a metal to an insulator. Atomic-scale control of the surface is achieved using molecular beams of atoms (the molecular beam epitaxy growth method). To understand why the thin film changes from a metal to an insulator, the surface is imaged using x-rays scattered from the film (see 3D image of film on left).
