The Quantum Hall Effect

THE QUANTUM HALL EFFECT Abstract The Quantum Hall effect (QHE) is the observation of the Hall effect in a two-dimensional electron gas system (2DEG) such as graphene and MOSFETs. It represents good example of physical systems where quantization effect could be observed microscopically as a result of the interplay of the topology, interactions of electron…

History of Atomic Theory

The atomic theory is developed since 2000 years ago the Greek philosopher Democritus proposed that there was a limit to how small one could be divide matter, this smallest matter indivisible particle was called “atom”. However this atomic theory of Democritus was criticized by Aristotle who proposed a model based on four basic “elements” of…
