WebThe finite potential well (also known as the finite square well) is a concept from quantum mechanics. It is an extension of the infinite potential well, in which a particle is confined … WebFinite Square well problem. An electron is confined to a finite square well whose “walls” are 8.0 eV high. If the ground-state energy is 0.5 eV, estimate the width of the well. E 1 = π 2 ℏ 2 m L 2 ⇒ L = π ℏ 2 m E 1 = π ( 1.055 × 10 − 34 J s) 2 ( 9.11 × 10 − 31 K g) ( 8 × 10 − 20 J) = 8.6813 × 10 − 10 m ≈ 0.87 n m.
