Electron Behavior

Overview
Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the...

The Uncertainty Principle

34.7K
Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

  • Observation and analysis of Coulomb Blockade phenomena in synthesized Au NPs.

Main Results:

  • Demonstrated Coulomb Blockade in Au NPs significantly larger than the typical <10 nm requirement.
  • Observed minimal dependence of blockade voltage on the overall NP size.
  • Identified ultrasmall, isolated single crystalline grains within polycrystalline NPs as the source of SET.

Conclusions:

  • Achieved single-electron tunneling (SET) in macroscopic gold nanoparticles, challenging established size limitations.
