Abstract
When you look closely, Nature is nanotechnology and quantum sensing at its finest. From a single cell, a factory all by itself, to complex systems, such as the nervous system or the human eye, each is composed of specialized quantum-structures that exist to perform a specific function. This same beauty can be mirrored when we interact with the tiny physical world which is the realm of quantum mechanics. Electrons, photons, and even thermal properties can all be engineered at this level. Using Nature as a template, we have already applied nanotechnology to improve traditional sensors (e.g. artificial eyes, ears, and noses). However, beyond this is the more general “quantum sensing” area, which allows us to think creatively about interacting with and exploring physical processes on a truly fundamental level. Possibly the simplest aspect of Quantum Science and nanotechnology, the 2-D quantum well has dramatically enhanced the efficiency and versatility of electronic and optoelectronic devices. While this area alone is fascinating, nanotechnology has now progressed to 1-D (quantum wire) and 0-D (quantum dot) systems which exhibit remarkable and sometime unexpected behaviors. With these components serving as the modern engineer’s building blocks, it is a brave new world we live in, with endless possibilities for new technology and scientific discovery. There is still so much to learn and to be curious about. In this talk, I will present the latest Quantum Devices based on atomic and gap engineering of III-V semiconductor from deep us: 200 nm up to THZ; 300 microns.
