We would like to propose a novel semiconductor material that can show both plasmonic and electric properties. Moreover, using smectite clay, whole structure of this material can be designed so that it is easily printed in any kinds of solvents. ABC semiconductor means the desirable composite of Ag nanoplate, boron, and clay. Plasma resonance is controlled around Ag plate surface by adjusting its size and the plasmon energy can be transferred to boron semiconductor and excite it. ABC semiconductor will pave the way for various applications, such as energy harvesting cells with storage effect, functional films that reflect or absorb only the light with specific wavelength up to infrared region, non-contact antibacterial coating by usage of strong electric fields induced by plasmon resonance, as well as SERS. In this paper, a photo-voltaic cell as one of applications has been studied.
Our photo-voltaic cell is completely different from conventional ones. When illuminated, Ag plasmon oscilation should induce charge accumulation to generate power, and that really occurred. The fact proves ABC semiconductor 's high potential.
We are now verifying ABC semiconductor should be open to other various possible applications.
