Although remarkable progress has been made [19-22], a complete theory of the quantum Hall effect
is still missing.

Coverage here encompasses the history of Si, MEMS, and NEMS, followed by discussion of crystallography, quantum mechanics, the band theory of solids, the silicon single crystal, photonics, the quantum hall effect
, and superconductivity.
The international standard for electrical resistance is provided by the Quantum Hall Effect
, a phenomenon whereby electrical properties in 2D materials can be determined based only on fundamental constants of nature.
Placing graphene samples in magnetic fields whose intensities the researchers ratcheted up, they saw the electrical resistance increasing in discrete steps, a phenomenon known as the quantum Hall effect
. Around the same time, a group led by Philip Kim of Columbia University made the same discovery after learning of Geim's tape-peeling technique.
