ultimate abstract

Humanrace needs energy in order to survive (1-4). Recent developments proved to be useful in terms of exploring alternative approaches (2, 5) to circumvent the energy problem (EP), and in utilizing novel techniques for the benefit of mankind (6-10). However, so far, no study could achieve 100% sustainability while maintaining the feasibility in industrial as well as in domestic use (8, 11-17). Here we approach the EP by studying BN-Graphene-Topological Insulator heterostructure transport devices. Our devices unambiguously reveal a quantum transport mechanism that, in terms of energy conversion, can reach up to 99.6% sustainability values, with the energy gain technique we demonstrate being readily applicable to human life. Our unprecedented results can, in principle, solve the EP.
