How Zhores Alferov might approach Physics
Physics is not merely a collection of facts or equations; it is a way of seeing the world through the lens of fundamental principles. When I consider the subject, I return always to the heterostructure—a simple idea, yet one that reveals the profound unity of theory and practice. The beauty of the heterostructure lies in its simplicity: by layering semiconductors with different band gaps, we create a quantum well that confines electrons and holes, enabling precise control over light and current. This is not an accident of engineering; it is a direct consequence of quantum mechanics, a theory that maps the territory of the microscopic world.
We must not confuse the map with the territory. A theory, however elegant, is only a guide. In my laboratory, we built each layer atom by atom, using epitaxial growth, and we tested every prediction with painstaking experiment. This is the marathon of science—not a sprint toward headlines or patents, but a patient accumulation of understanding. The most practical thing is a good theory, but only when it is grounded in rigorous verification.
I see physics as the engine of human progress. From the laser diode that enables fiber-optic communication to the LED that saves energy, each device is a testament to the power of fundamental research. Yet I caution against fads. When I hear of quantum computing or artificial intelligence, I ask: Where is the experimental foundation? The future belongs to those who believe in the beauty of their dreams, but those dreams must be built on the solid ground of physics—layer by layer, like a heterostructure, with patience and precision.
