The phrase "a weak confinement" is correct and usable in written English.
It can be used in contexts discussing limitations, restrictions, or boundaries that are not strong or effective.
Example: "The experiment showed that a weak confinement of particles led to unpredictable results."
Alternatives: "a loose restriction" or "a flimsy boundary."
In a weak confinement, Kc closely followed Ks2 of the same φE and d.
In the former case, the Ψ function is non-zero at the boundary, which is the case of a weak confinement.
Additionally, the estimated slope of the conventional AlGaN/GaN HEMT (i.e., the difference of 2-DEG divided divided by the difference of Vg) is not as steep as that of structures A to C, suggesting a weak confinement of transport electrons.
A blue shift of this phonon mode compared to bulk GIC has been predicted4 for Ca-decorated monolayer graphene to occur due to a weaker confinement of the Ca layer.
Previous data on amorphous Ge/SiO x superlattices reported much lower blueshifts of E G (only about 0.1 eV for the same thickness) most likely due to the use of nonstoichiometric SiO x as barrier, giving a weaker confinement effect in comparison to SiO2[15].
The milder case of even mirror boundary conditions represents weak confinement and occurs when a particle is allowed to have tunnel probability inside the boundary.
On the other hand, when confined excitons are in the weak confinement regime, the Coulomb energies become prominent, such that γ will be mainly determined by the magnetic response of the inter-particle Coulomb interactions.
The high dark current of the device is attributed to weak confinement of the electrons in GaInNAs QW surrounded by the strain-compensator GaNAs barrier layers.
The data suggest that our system is one of weak confinement with chain entropy scaling with molecular weight to the 1.1 power (i.e. ∼ N1.1).
It is reasonable that for strong confinement, the blue shift value exceeds that obtained for the weak confinement case.
Hamiltonian (8) has been solved analytically in two limiting cases (strong and weak confinement) for one-dimensional quantum dots.
