The dimensions of these wires are too large to exhibit electron/phonon confinement [1, 2].
In the past years, there has been a surge of interest in structures that exhibit quantum confinement in all three dimensions, commonly known as quantum dots (QDs).
In the past several years, there has been a surge of interest in nanostructures that exhibit quantum confinement in three dimensions, which are known as quantum dots (QDs).

They exhibit quantum confinement effect such as size-dependent optical and electric properties for applications in optoelectronic devices [1 3] and biological fluorescence labeling [4, 5].
Carbon dots- or wire-like nanostructures comprise of carbon structures exhibit quantum confinement when one dimension is less than 10 nm while carbon nanodots (CNDs) ascribed to almost spherical nanoparticle is a topic of extensive research interest.
In contrast, self-assembled QDs can exhibit strong confinement and localization energy [4],[5] resulting in an orbital level spacing energy of up to 80 meV and Coulomb charging energy of about 20 meV.
Silicon in the form of tiny Si-ncs, which exhibit quantum confinement effects, offers unique properties: i.e., the Si-ncs can serve as electron acceptors [5, 6] and can produce multiple electrons per photon due to the carrier multiplication that can increase photocurrent generation [7].
The deepest aquifer layer (A2 CAS) has a top covering layer of clay sediments and exhibits greater confinement, especially towards the south of the area.
Regarding the nanoparticles exhibiting quantum confinement, increasing the nanoparticle of size influenced the bandgap decreasing with the temperature from 400 to 500 °C [25].
