QE (CLASS 438)
quantum efficiency

QFP (CLASS 438)
quad flat package

QUANTIZED STATES (CLASS 257)
Discrete energy levels due to the quantum mechanical properties of a material.

QUANTUM CELL (CLASS 977)
Structure comprising four quantum dots arranged in a square, with two diagonally opposed dots containing electron charges. One diagonal containing charges is arbitrarily defined as representing a value of "1", the other as "0"; in a five-dot cell, the fifth, central dot contains no charge.

QUANTUM CELL WIRE (CLASS 977)
Wire in which information is transferred by a change in orientation of quantum cells arranged in a line as opposed to utilizing electron flow.

QUANTUM COMPUTING (CLASS 977)
Computing scheme dependent upon wavelike properties of elementary particles.

QUANTUM DOT (CLASS 977)
Broadly, a structure that promotes confinement of electron(s)/hole(s) in three dimensions; alternatively, a location capable of containing a single electron charge; synonymous with single electron transistor, qubit, and quantum bit.

QUANTUM ENTANGLEMENT (CLASS 977)
The process of combining two separate pieces of information so that they can be treated as a single entity; a correlation between quantum states, e.g., spin, polarization, etc., of two or more particles.

QUANTUM TRANSISTOR (CLASS 257)
Transistors whose operation is based on the properties of electrons confined in quantum wells - semiconductor films only a hundred or so angstroms thick sandwiched between high confining walls made of a second semiconductor material.

QUANTUM TRANSISTOR (CLASS 438)
Transistors whose operation is based on the properties of electrons confined in quantum wells - semiconductor films only a hundred or so angstroms thick sandwiched between high confining walls made of a second semiconductor material.

QUANTUM TUNNELING (CLASS 977)
Effect of transferring of particles through a potential barrier larger than the particles total energy that occurs based upon the barrier thickness and the difference between the potential barrier energy and the particle energy.

QUANTUM UNCERTAINTY PRINCIPLE (CLASS 977)
Principle stating that the position of a particle and its momentum, or alternatively, energy of the particle and time of measurement; cannot be simultaneously measured with arbitrary precision; noted to not be a significant factor at length scales above the level of an atom.

QUANTUM WELL (CLASS 257)
Semiconductor films only a hundred or so angstroms thick sandwiched between high confining walls made of a second material.

QUANTUM WELL (CLASS 438)
Semiconductor films only a hundred or so angstroms thick sandwiched between high confining walls made of a second material.

QUANTUM WELL (CLASS 977)
Broadly, a structure that promotes electron or hole confinement in one dimension so that the electron or hole can only propagate with two degrees of freedom; with respect to semiconductor physics, a semiconductor heterostructure utilizing a narrow bandgap semiconductor sandwiched between two layers of a larger bandgap semiconductor; alternatively, a potential well that confines particles within a planar region wherein the width of the region is on the order of the De Broglie wavelength of the particles.

QUANTUM WIRE (CLASS 977)
Structure that promotes electron or hole confinement in two dimensions so that the electron or hole can only propagate with one degree of freedom.

QUARTZ (CLASS 117)
SiO2; silicon dioxide; silica. Polycrystalline forms include agate, cat's eye, chalcedony, and jasper. Crystalline forms include amethyst, catalinite, citrine, rose quartz, and smoky quartz.

QUARTZ (CLASS 428)
A fused silicon dioxide (silica). (Nonstructural or Composition)

QUARTZ, FUSED (CLASS 117)
Vitreous or glassy quartz.

QUERY (CLASS 707)
A request for data, typically used in database management systems to find data.

QUIP (CLASS 438)
quad-in-line package

QUIRE(*) (CLASS 412)
A term of art meaning 24 sheets(*) of paper.

QW (CLASS 438)
quantum well

QWIP (CLASS 438)
quantum well infrared photodetector
