Description
Nanophysics operates in between quantum behavior and classical physics governed by Newton's and Einstein's laws. More accurate definition, nanophysics studies the physics of structures with dimensions in the nanometer range and phenomena that occur in the nanosecond. Nanophysical properties include nanomaterials' structural, electronic, optical, and thermal behavior. Nanophysics deals with objects consisting of atoms, atomic clusters and nanoparticles, nanowires, and thin films. Nanophysics helps describe, measure, and understand the properties of individual molecules, atoms, and electrons. This course teaches fundamentals of physics relevant to a better understanding of nanotechnology. Nanophysics research concerns many quantum physics concepts analyzed, for example, using spectroscopic methods. Classical physics experiments and theory are discussed, starting from blackbody radiation, photoelectric effect, de Broglie wavelength, Heisenberg uncertainty principle, Bohr atomic model, hydrogen atom, quantum wavefunction, electron configuration, quantum, and multi-electron atoms. Nano-physicists also work on creating artificial atoms and molecules, i.e., "quantum dots". A quantum dot is a nanoparticle that confines electrons, and electrons have quantized energy levels like those in atoms. The hydrogen atom, with one proton in its nucleus and one electron, is the simplest example of nanophysics. Nanophysics led to discoveries including the quantum Hall effect in 2D nanomaterials, the application of the quantum tunneling effect in Scanning Tunneling Microscopy and graphene, carbon nanotube, and fullerene.
