What was a key property of the heterostructures Alferov researched?
Magnetic
Acoustic
Thermal
Electrical Conductivity
Answer
The essence of Alferov's heterostructure research lies in the precise control of electrical conductivity. By meticulously engineering the composition and arrangement of semiconductor layers, he created structures where the flow of electrons and holes, the fundamental charge carriers in semiconductors, could be precisely tailored. This breakthrough enabled the development of highly efficient optoelectronic devices like lasers and solar cells, revolutionizing fields from telecommunications to energy production.
