Understanding Ballistic Transport Phenomena
As electronic devices get smaller, Quantum Transport and Electron Ballistics become more important. In nanoscale electronics, transistors are getting so small that electrons can travel without being scattered. This is called ballistic transport.
How Ballistic Transport Works
Ballistic transport happens when electrons move through a transistor without being scattered. This is because the transistor is so small that electrons keep their energy and speed. This is due to the wave-like nature of electrons, as explained by quantum mechanics.
The Role of Quantum Mechanics
Knowing quantum mechanics is key for making better ballistic velocity transistors. In this regime, electrons act like waves, moving faster and losing less energy. This is because they don’t scatter as they travel through the transistor.
| Statistic | Value |
|---|---|

| Commercial microprocessors have transistors with lateral feature sizes below 100nm | – |
| Thinnest material films are below 2nm | – |
| Current chip-level power densities | Approximately 100 W/cm^2 |
| Chip-level power density is expected to increase further | – |
