ETE411 :: Semiconductor
The Uncertainty Principle
• First statement: it is impossible to simultaneously describe with absolute accuracy the position and momentum of a particle.
Modified Planck's constant
second statement
• it is impossible to simultaneously describe with absolute accuracy the energy of a particle and the instant of time the particle has this energy.
the uncertainty principle is only significant for subatomic particles.
SCHRODINGER'S WAVE EQUATION
• The Wave Equation: The one-dimensional, nonrelativistic Schrodinger's wave equation is given by,
The Potential Barrier
The wave functions through the potential barrier
