If the diameter of a wire is sufficiently small, electrons will experience quantum confinement in the transverse direction.
This effect of quantum confinement on the quantum dots have been experimentally verified and is a key feature of many emerging electronic structures.
Other size-dependent property changes include quantum confinement in semiconductor particles, surface plasmon resonance in some metal particles and superparamagnetism in magnetic materials.
Peculiar features of this quantum confinement exhibited by certain nanowires manifest themselves in discrete values of the electrical conductance.
Some research is also being done to create quantum dots by changing the width of GNRs at select points along the ribbon, creating quantum confinement.
This situation of discrete energy levels is called quantum confinement.
This size control creates quantum confinement and allows for the tuning of optoelectronic properties, such as band gap and electron affinity.
For that, you needed an antimatter explosion, and therefore more-than-modest supplies of stabilized positronium in quantum confinement.
A quantum well laser is a laser diode in which the active region of the device is so narrow that quantum confinement occurs.
CdSe-derived nanoparticles exhibit with sizes below 100 nm exhibit a property known as quantum confinement.
