In a study recently published in the journal ACS Nano, published by American Chemical Society, researchers from Kanazawa University, Kanazawa, Japan, collaborating with University of Washington, Seattle, USA, used frequency modulated atomic force microscopy to reveal the molecular architecture of a genetically designed peptide and its self-organization that forms single-molecule thick crystals on atomically flat graphite surfaces, that offer a potential platform for hybrid technologies such as bioelectronics, biosensors, and protein arrays.

Osaka Metropolitan University scientists succeeded in directly observing how LECs—which are attracting attention as one of the post-organic LEDs—change their electronic state over time during field emission by measuring their optical absorption via lamp light irradiation for the first time. This research method can be applied to all light-emitting devices, including not only LECs but also organic LEDs. This method is expected to reveal detailed electroluminescence processes and lead to the early detection of factors that reduce the efficiency of electroluminescence.
