Spin (physics)
In physics, spin refers to
the angular momentum
intrinsic to a body, as
opposed to orbital angular
momentum, which is generated
by the motion of its center
of mass about an external
point. ... > full story
Quantum number
A quantum number describes
the energies of electrons in
atoms. Each quantum number
specifies the value of a
conserved quantity in the
dynamics of the quantum
system. Since any quantum
system can have one or more

Semiconductor
A semiconductor is a
material with an electrical
conductivity that is
intermediate between that of
an insulator and a
conductor. A semiconductor
behaves as an insulator at
very low temperature, and
... > full story
Subatomic particle
A subatomic particle is a
particle smaller than an
atom: it may be elementary
or composite. Particle
physics and nuclear physics
concern themselves with the
study of these particles,
their interactions, and
... > full story

Atomic orbital
Atomic orbitals are the quantum states of the individual electrons in the electron cloud around a single atom. Specifically, atomic orbitals are the quantum states of the individual electrons in the ... > more -
Electrical conduction
Electrical conduction is the movement of electrically charged particles through a transmission medium. The movement can form an electric current in response to an electric field. The underlying ... > more -
Scanning tunneling microscope
The scanning tunneling microscope or STM, was invented in 1981 by Gerd Binnig and Heinrich Rohrer of IBM's Zurich Lab in Zurich, Switzerland. t is used to obtain images of conductive surfaces at an ... > more -
Electron microscope
The electron microscope is a type of microscope that uses electrons to create an image of the target. It has much higher magnification or resolving power than a normal light microscope. Although ... > more -
Hydrogen-like atom
Hydrogen-like atoms (or hydrogenic atoms) are atoms with one single electron. Like the hydrogen atom, hydrogen-like atoms are one of the few quantum mechanical problems which can be exactly ... > more -
Electron configuration
In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). Like other elementary ... > more -
Quantum tunnelling
Quantum tunnelling (or tunneling) is the quantum-mechanical effect of transitioning through a classically-forbidden energy state. Consider rolling a ball up a hill. If the ball is not given enough ... > more
