New Results Reveal Extensive Tunability of 2-D Materials

Scientific Achievement

Molecular Foundry users and scientists have developed a new method to directly measure the band gap of MoS2, which is 30% higher than expected. The study also discovered how to tune optical and electronic properties in a 2-D material.

Significance and Impact

This is the first time the MoS2 band gap has been measured; the band gap is vital for properly connecting 2-D materials in a device. MoS2 is sensitive to both optical and electronic effects and will enable creation of ultrasensitive sensors and smaller transistors.
