Hi! Let's suppose an electron in a mono-dimensional potential well. According to Heisenberg uncertainty principle, if L is the length of the well, then I have a momentum greater than [tex]\frac{h}{L}[/tex], which means that the electron has a velocity (and so a kinetic energy) greater than [tex]\frac{h}{L*m_e}[/tex]. If I "press" the well, L becomes smaller and smaller, so the kinetic energy of the electron becomes greater and greater; according to the conservation of energy, the electron must take this energy somewhere: where does the electron take the energy needed to increase its kinetic energy?(adsbygoogle = window.adsbygoogle || []).push({});
