Professor Patané, who led the sensor development, explains what makes the results stand out: "This work combines for the first time the generation of femtosecond UV-C laser pulses with their fast detection by 2D semiconductors. Unexpectedly, the new sensors exhibit a linear to super-linear photocurrent response to pulse energy, a highly desirable property, laying the foundation for UV-C-based photonics operating on femtosecond timescales over a wide range of pulse energies and repetition rates."

From Science Daily

Tim Klee, a PhD student at Imperial, adds that ease of use and accessibility will be critical moving forward: "A compact, efficient and simple UV-C source will benefit the wider scientific and industrial community, stimulating further research on UV-C photonics."

From Science Daily
