Description
Xin Wang and co-authors report a 2026 study of light sensors built from a two-dimensional material called MoTe2. Such thin crystals can turn light into current for cameras and smart sensors that see from visible light into the near infrared.
Heating the devices in air at set temperatures healed flaws in the crystal and more than tripled one key transport measure. The tuned sensor answered light strongly, with an external quantum efficiency of 652 percent at one test wavelength. A paired device with MoSe2 also gave clean switching and very low dark current. The results point to cheap, sharp light sensors for future gadgets.
