Example Sentences

In this proof of concept, information was encoded into the UV-C laser by the source-transmitter and then successfully decoded by the 2D semiconductor sensor acting as the receiver.

From Science Daily

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

Ben Dewes, a PhD student at Nottingham, points out that this area of research is still emerging: "The detection of UV-C radiation with 2D materials is still in its infancy. The ability to detect ultrashort pulses, as well as to combine the generation and detection of pulses in free-space, helps pave the way for the further development of UV-C photonic components."

From Science Daily

The strong sensing performance of 2D materials supports the development of integrated platforms that combine light sources and detectors into a single system.

There have even been Austen-inspired online role-playing games such as the now-defunct “Ever, Jane,” as well as a 2D platformer game in which Austen uses a quill to fight off villains based on characters from her various novels.
