Mxene Photodetectors: Beyond Gold: Spin‐Coated Ti3C2‐Based MXene Photodetectors (Adv. Mater. 43/2019)

“As good as gold” is a seldom true adage, but in article number 1903271, Bahram Nabet and co-workers show that using a Ti3C2Tz (MXene) aqueous suspension, a table-top spinner, and acetone, GaAs photodetectors that outperform conventional ones using Ti/Au can be fabricated. This ambient condition process is promising for integration into microelectronics, photonic integrated circuits, and silicon photonics technologies.
