What was his major contribution in the field of surface physics?
Heat Transfer
Sound Reflection
Theory of elasticity
Quasiparticle Phonons
Answer
Quasiparticle phonons represent a groundbreaking concept in surface physics, introduced by this renowned physicist. They describe the quasiparticles that emerge from the collective motion of atoms on a crystal's surface, behaving like "sound waves" within the atomic lattice. This discovery deepened our understanding of the fundamental behavior of surfaces, paving the way for advancements in various fields, including catalysis, nanotechnology, and materials science.
