초록 | Based on multidisciplinary convergence research, new materials and devices for smart human adaptive interface on green technology coping with future environmental pollution and resource exhaustion as well as, silver technology for aging generation are mainly investigated and developed. In our center, diverse ideas through experiments and quantum chemical methods are studied and achieved to realize the new opto-electronic materials and devices. Soft electronics as a promising candidate for next generation industry, and its related core materials such as semiconductor nano quantum dots(QDs), metal nano wire/rod, nanocarbons (graphene etc.), polymer hybrid as well as flexible optoelectronic devices, nanophotonics, and printing process are being investigated. We also improve the performance of optical devices such as laser diodes and LEDs as well as to develop new functional devices such as single photon sources by using semiconductor quantum dots, quantum wells, nanowires or photonic crystals. We grow the semiconductor-based epi-structures and nanomaterials: Quantum dots, Quantum wells, Nanoparticles, Nanowires, etc. In our research center, 2-dimensional (2-D) nanomaterials such as graphene and black phosphorus are explored and synthesized. Especially, passively mode-locked fiber lasers for the femtosecond duration of the laser output are realized based on the 2-D nanomaterials that display high optical nonlinearity. (J.A.Im, W.K.Choi, Y.W.Song, ACS Nano, 8 2014 p11753). Organic solar cell with Ag nanowire electrodes and PTB7:PC70BM active layer shows the Jsc of 20 mA/cm2 resulting in the PCE of 7.99 %. (B.Wang, D,K.Hwang, Y.J.Oh, Small 20140261, 2014.) Counter-clockwise bipolar resistance switching memory current-voltage (I–V) characteristics are observed within the switching voltage window of 22.5 to 11.9 V with good endurance and retention properties. (J.K.Lee, H.Im, Sci. Rep. DOI 10.1038/srep07354, 2014) MBE Growth and characterization of noble bulk materials (3-D), 2DEG/2DHG (2-D), nanorods (1-D), and quantum dot/ring (0-D) structures for application to photonic and electronic devices are investigated.(S.H.Kim, J.D.Song, W.J.Choi , Electon. Lett. 53(23) 2014 p1731.) |
