Different Types of Heterostructures ;
Heterostructures can be classified based on the materials used to prepare them into five categories:
(i) metal or semimetal/semiconductor-based heterojunctions; (ii) semimetal/insulator-based
heterojunctions; (iii) semiconductor/semiconductor-based heterojunctions; (iv)
semiconductor/insulator-based heterojunctions; and (v) metal/semimetal-based heterojunctions.
Among these, metal or semimetal/semiconductor-based heterojunctions have gained much
attention from researchers. We describe highlights of the latest trends in metal or
semimetal/semiconductor-based heterostructures for better understanding of the structural
features with respect to their synthesis procedures
