Atomic-scale electronics in semiconductors Gert-Jan Smit
... The size of a hydrogen atom is defined by its Bohr radius, which is only half an Angstrom. A dopant atom in a semiconductor—considered as the solid state analogue of a hydrogen atom—has a Bohr radius of several nanometers. Nowadays semiconductor technology has arrived at the edge of the regime where ...

Solid effect in magic angle spinning dynamic nuclear polarization Please share
... Equation (20) is derived for ω0I A, B, and, since A and B decrease with increasing distance between the electron and the nuclear spins, it is only valid for nuclei which reside a certain radius from the electron spin. However, in a high magnetic field, this condition is satisfied for all protons o ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
