By [Elliot Clark](https://energytheory.com/author/elliot_clark/)November 17, 20232 Mins Read ![JAN23 What is Barrier Energy](https://energytheory.com/wp-content/uploads/2023/02/What-is-Barrier-Energy-1024x683.jpg "What is Barrier Energy?") The barrier energy is the **energy expended by an electron as it crosses the cell membrane**; it serves as a gauge for the barrier’s electrostatic potential. A potential field known as an energy barrier can be used to **localize or control the movement of charged particles**, such as electrons. Every component necessary to build micron-scale systems like the nanomorphic [cell](https://energytheory.com/what-is-half-cell-solar-panel/) depends on energy barriers to function. On the probability of nuclear barrier penetration, the action of the surrounding electrons is taken into account. For heavy atoms, **the nuclear potential is swapped out for the [Fermi-Thomas](https://www.sciencedirect.com/topics/chemistry/thomas-fermi-model) potential**, and for very light atoms, for a potential derived from a constant electron-density model. **What is Electric Potential Energy?** The power required to **move a charge in opposition to an electric field** is known as electric potential energy. A charge must be moved through a stronger electric field with more energy, but it also must be moved through a weaker electric field with more energy. Consider a large negatively charged plate that has a little positively charged particle attached to it by the force of electricity. The plate has an electric field surrounding it that is attracting any items that are positively charged (while pushing other negatively charged objects away). **Also Read:**  [What is Band Gap?](https://energytheory.com/what-is-band-gap/) In spite of the electric field’s force, you begin to drag the positive particle away from the plate. The electric force is drawing them together, making it difficult to work. The electric force would bring the **positive particle back to the negative plate** if you let it go. The particle stores the energy you used to propel it away from the plate as electrical potential energy. When a particle is released, it has the ability to migrate. Share.
