Intro to Nanotechnology

Definition

The Schrödinger Equation is a fundamental equation in quantum mechanics that describes how the quantum state of a physical system changes over time. It encapsulates the wave-particle duality of matter, demonstrating that particles such as electrons can exhibit both wave-like and particle-like properties, which is essential for understanding phenomena at the nanoscale.
