A region in a field of force, in particular the region in which an atomic nucleus is situated, in which the potential is significantly lower than at points immediately outside it, so that a particle in it is likely to remain there unless it gains a relatively large amount of energy.
〔物理〕势阱，电位阱
Example sentencesExamples
This lattice can trap the neutral atoms in potential wells because the electric fields of the lasers induce a dipole moment in the atom.
Engineers can control the colour of the light emitted by the laser simply by adjusting the energy levels within the central sheet, which acts as a potential well.
Then, by applying an electric field perpendicular to these layers, you create a potential well which can confine electrons along this perpendicular direction.
The defects produce a potential well which holds the electrons in them.
Each particle thus diffuses in a potential well and its movement is simulated using a Brownian dynamics algorithm.
