nanoHUB-U: Fundamentals of Nanotransistors, 2nd Edition

Course Description:

The modern smartphone is enabled by a billion-plus nanotransistors, each having an active region that is barely a few hundred atoms long. Interestingly the same amazing technology has also led to a deeper understanding of the nature of current flow on an atomic scale and my aim is to make these lessons from nanoelectronics accessible to anyone in any branch of science or engineering.

nanoHUB-U: Biological Engineering - Cellular Design Principles

Introductory video provides a nice overview of the size and scale of a cell with respect to its environment and its components, and questions we may ask if a cell were to be used as a factory.

Course Description:

A self-paced course on the design principles underlying mechanisms of cellular and biomolecular functions such as cell architecture, energy storage and conversion, sensing and signaling, communication, time keeping, molecular synthesis, memory, and motility.

The photon is the ultimate unit of information because it packages data in a signal of zero mass and has unmatched speed. The power of light is driving the photonicrevolution, and information technologies, which were formerly entirely electronic, are increasingly enlisting light to communicate and provide intelligent control. Plasmonic nanophotonics promises to create entirely new prospects for guiding light on the nanoscale, some of which may have revolutionary impact on present-day optical technologies.

\“Electronics\” uses our ability to control electrons with electric fields via interaction with their fundamental charge. Because we can manipulate the electric fields within semiconductors, they are the basis for microelectronics, and silicon (Si) is the most widely-used semiconductor for integrated microelectronic circuits. The electron\‘s magnetic moment, called spin, has been known for over eighty years, and its existence explains (among other things) the static magnetic field of permanent magnets. Our understanding of electron spin manipulation has led to information-storage applications such as high-sensitivity magnetic field sensors for hard-drives (Giant Magneto-Resistance – or GMR – devices), and devices for non-volatile random-access memory called Tunnel Magneto-Resistance (TMR) devices; however, it has not yet found use in information-processing circuits. To enable spin-based integrated circuits, long spin lifetimes are necessary to enable multiple logic operations before depolarization and decoherence sets in. In addition, long spin transport coherence lengths are needed to enable integration of multiple devices in a circuit. Silicon has been broadly viewed as the ideal material for spintronics due to its low atomic weight, lattice inversion symmetry, and near lack of nuclear spin. Despite this appeal, however, the experimental difficulties of achieving coherent spin transport in silicon were overcome only recently (in our lab here at Delaware), by using unique spin-polarized hot-electron injection and detection techniques with nano-scale ferromagnetic metal spin \“polarizers\”.1 Using these methods, we have observed unprecedented coherence in spin precession measurements, and extracted very long spin lifetimes of conduction electrons traveling over macroscopic distances.2 Whereas transistor scaling limits will soon suppress progress in microelectronics using Si, its favorable spintronics properties may secure this semiconductor\‘s dominance for the future.

I will discuss recent progress in experimental techniques to control the orientations of nanoscale magnetic moments and electron spins, and to use these new means of control for applications. One powerful new capability arises from the fact that thin magnetic layers can act as filters for spins.

First, I will discuss the physics and applications of 2D heterostructures composed of stacked monolayers of MoSe_2 and WSe_2 . These heterostructures host interlayer valley excitons where the electrons and holes are located in different layers. These spatially indirect excitons exhibit long lifetimes and valley polarization times which are promising for valley based information applications and for investigating long-range spin transport phenomena. Second, I will discuss single excitons localized to defects in monolayer WSe_2 , which are shown to be single photon emitters. I will discuss the physics of these localized quantum states as well as their potential quantum photonics applications....

In recent years, in my group we have been working on various aspects of metamaterials and plasmonic nano-optics. We have introduced and been developing the concept of \“metatronics\”, i.e. metamaterial-inspired optical nanocircuitry, in which the three fields of \“electronics\”, \“photonics\” and \“magnetics\” can be brought together seamlessly under one umbrella – a paradigm which I call the \“Unified Paradigm of Metatronics\”. In this novel optical circuitry, the nanostructures with specific values …

Water purification with nanotechnology

A cartoon poster about how water can be purified using nanotechnology. Scientists make tiny silver particles, called nano silver. These are used to clean water because they are antibiotics. This means that they kill bacteria, such as E.coli, which causes diseases and sometimes death. You can get plastic water barrels that contain nano silver particles. The nano silver particles combine with the cell walls of the bacteria, and stop them from getting oxygen. In other words, they suffocate the bacteria. If you leave water in the barrel for a few hours, all the harmful bacteria will be killed.
