제목 Optical Band Gap and Hall Transport in Lanthanide-Ion Modified DNA Crystals
초록 We have studied the optical band gap and Hall transport in lanthanide-ion-modified DNA crystals fabricated on quartz and silica substrates via surface-assisted growth. The optical band gap of these crystals exhibits a dependence on ion species and the second band onset showed an inverted V shape upon increasing the lanthanide ion concentration. Each lanthanide-ion-doped DNA crystal shows low Hall mobility, high free-carrier concentration, and low resistivity at a critical concentration. Our research paves a way to control the optical band gap and Hall parameters of DNA crystals by adjusting the concentration of the lanthanide ions.
