Phototropic and skototropic growth in inorganic films

We report herein phototropic growth toward, and skototropic growth away from, an incoherent, unstructured, low-intensity light stimulus in the deposition of nonliving, inorganic material. Fundamental light–matter interactions yield growth of inorganic deposits with ordered mesost...

Electro-optic modulation of coherent and incoherent mid-IR radiation in two-dimensional arrays

Light in the mid-infrared (mid-IR) spans wavelengths from 3 to 8 micrometers and is important to many applications such as gas sensing and thermal imaging. Due to materials challenges, there is now a lack of mid-IR reconfigurable optical elements. Here, we present an electrically...
