Eduard Driessen, MSc, and Dr Michiel de Dood's new paper in Applied Physics Letters identifies a new contender for the blackest material that ever existed. No word on whether it's any blacker than the last three Spinal-Tap-joke-inspiring none-more-black materials we've covered here since 2003.
Two researchers, Eduard Driessen, MSc, and Dr Michiel de Dood, have demonstrated that at a thickness of 4.5 nanometer niobiumnitride (NbN) is ultra-absorbent. They have recorded a light absorption of almost 100%, while the best light absorption to date was 50%. This research brings the ideal light detector a step closer.
