A region within a force field in which the potential is significantly higher than at points either side of it, so that a particle requires energy to pass through it.
〔物理〕垫垒，位垒
Example sentencesExamples
It is argued that the low dielectric permittivity of the surface water leads to a potential barrier for ions, which is high enough to be important for biological energy transduction.
Here we showed that the low dielectric permittivity of interfacial water leads to a potential barrier for ions moving between the surface and the bulk water phase.
There are radioactive nuclei that behave as if they contain certain constituents, called particles, that are trapped within the nucleus by a potential barrier generated by the nuclear forces.
As long as the surface tension in the drop is larger than the repulsive Coulomb force due to the protons, a potential barrier prevents it from splitting.
Electrostatic calculations revealed a potential barrier in the water phase some 0.5-1 nm away from the membrane surface.
