DOI: 10.1021/jacs.2c12320
Abstract: The design and regulation of multiple room-temperature phosphorescence (RTP) processes are formidably challenging due to the restrictions imposed by Kasha’s rule. Here, we report a general design principle for materials that show multiple RTP processes,… read more here.

DOI: 10.1038/s41598-020-70697-5
Abstract: Retinal proteins play significant roles in light-induced protons/ions transport across the cell membrane. A recent studied retinal protein, gloeobacter rhodopsin (gR), functions as a proton pump, and binds the carotenoid salinixanthin (sal) in addition to… read more here.

DOI: 10.1103/physrevb.99.085307
Abstract: We study the interlayer scattering mediated by long-range Coulomb interaction between electrons (density $n)$ and holes $(p)$ in a double-layer system. The gated device is made of InAs $(e)$ and InGaSb $(h)$ quantum wells separated… read more here.
