Key ideas in Quantum Physics in Your Pocket
- Metals always allow electricity to flow and cannot be turned off
- Semiconductors can be toggled between conducting and insulating states
- Why semiconductors are used for switching instead of metals
- Energy gaps act as physical barriers for electrons
- The size of the gap determines if a material can switch states
- The relationship between energy gaps and electron flow
- Transistors use electric fields to change material properties
- Switching happens by changing energy levels, not moving parts
- Electrons need an external energy push to cross a gap
- Crossing the gap is the requirement for current to flow
- The process of an electron crossing a semiconductor barrier
- Moving across gaps releases energy as heat
- The state of the gate (on or off) represents digital data
- The mechanism of a transistor as a gatekeeper
- Consequences of electron energy movement in transistors
- Electricity pushes electrons into the material
