A potential well, also known as a potential energy well, is a region in space where the potential energy of a particle is lower than its surrounding areas. This creates a force that attracts particles towards the center of the well.
The two main types of potential wells are single-well and double-well. Single-well potential wells have one minimum potential energy point, while double-well potential wells have two minimum points.
Potential wells have various applications in physics, chemistry, and engineering. They are used in particle accelerators, atomic and molecular physics, and in designing electronic devices such as transistors and diodes.
The depth of a potential well is determined by the difference between the potential energy at the minimum point and the potential energy at infinity. The deeper the well, the stronger the force of attraction towards the center.
A particle in a potential well will oscillate back and forth around the minimum point, with its kinetic energy increasing as it moves away from the center and decreasing as it moves towards the center. If the particle has enough energy, it may escape the well and move towards infinity.
