How do Franck's ideas on atomic energy levels relate to modern technology?
The principles we uncovered through experiments like the Franck-Hertz are foundational to much of modern technology. Let us first observe what nature tells us. The understanding of quantized energy levels in atoms and molecules is absolutely critical. The evidence suggests that technologies like lasers, which rely on the precise excitation and emission of photons from specific energy levels, would be impossible without this knowledge. Similarly, semiconductor physics, the basis of all modern electronics, directly utilizes the quantum mechanical understanding of electron energy bands within materials. Our early work laid the groundwork for these advancements.
