HOME > Researches
The group pursues original researches of state-of-the-art cutting edge technologies. Reproduction of the previously demonstrated works or their related similar results will not be able to entitle any candidate student to be awarded postgraduate degrees (Master or Ph.D) according to the Gachon university policy. In principle, new original ideas should be created by candidate students, but the supervisor will help students greatly with the generation of new ideas for their research upon a student request. The group research activities can be subdivided into the following areas:
  • (1)Development of photodetectors or photovoltaic devices using non-equilibrium heated carriers : use of plasmons decay into hot carriers for high efficiency device
  • (2)Development of display pixels using subpicosecond thermalized hot carriers generated from quantum dots-plasmon coupling : use of quantum dot-plasmon coupling for fast responding devices
  • (3)Development of Ultrahigh-sensitivity optical biosensors based on plasmon hot-carrier dynamics : immonoassay detection of sex hormones (17-beta estradiol and testosterone) in human urine for    early diagnosis of precocious puberty
  • (4)Plasmon-enhanced magneto-optical devices : optical memory, isolators and motors
