Tunneling structures

Tunneling structures are specialized electronic components that allow particles like electrons to pass through barriers that would normally block them, due to quantum mechanics. Think of it as a tiny shortcut through an obstacle instead of going around it. These structures, often used in advanced electronic devices, enable precise control of electron flow at very small scales, enhancing performance and enabling technologies like quantum computers and ultra-fast transistors. They rely on the wave-like nature of particles, which occasionally gives them a probability to "tunnel" through barriers even without enough energy to overcome them conventionally.
