Light‐Emitting Devices
A color‐tunable light‐emitting diode is realized by Jiang Pu, Yasumitsu Miyata, Taishi Takenobu, and co‐workers in article number 2203250 using compositionally graded monolayer transition metal dichalcogenide alloys. By controlling the light‐emitting positions in the alloys, the composition gradient of the bandgap enables continuous and reversible light emission with energies...
The diverse series of transition metal dichalcogenide (TMDC) materials has been employed in various optoelectronic applications, such as photodetectors, light‐emitting diodes, and lasers. Typically, the detection or emission range of optoelectronic devices is unique to the bandgap of the active material. Therefore, to improve the capability of these devices, extensive efforts have been devoted to...
