A flexible photodetector using asymmetric 2D heterostructures switches spectral response by gate voltage, enabling ...

Overcoming the limitations of wet processes that damage lithium surfaces and induce dendrites, the research team implemented a stable interfacial layer through a solvent-free transfer printing process ...

Traditional semiconductors such as Si, GaAs, and HgCdTe seem unable to meet the development trend of electronic devices that feature ultra-small volume, light weight, and low power consumption. These ...
