Experimental investigation of microwave power transduction based on Berry curvature

Harnessing quantum properties in macroscopic materials offers new technological opportunities. A recent example is the Berry curvature dipole, which arises from the dipolar distribution of Berry curvature—a geometric property of quantum wavefunctions. This “quantum dipole” can enable applications similar to charge dipole-based pn diodes, such as rectification and energy transduction, including converting solar, thermal, or microwave radiation energy into electricity. In this work, we investigate microwave power transduction based on Berry curvature in 2D materials from the MM’Te4 family.
