Abstract: α-Fe2O3 nanocrystal was encapsulated by a block-copolymer, hydroxylated poly (styrene-b- butadiene-styrene) (HO-SBS) to fabricate composite microspheres with α-Fe2O3 cores and HOSBS shell.Its film fabricated on n-Si wafer acts as the insulator layer in the metal-insulator- semiconductor(MIS) structure.The capacitance-voltage (C-V) properties were measured to characterize the composite particulate films.

Key words: α-Fe2O3 nanocrystal/block-copolymer composite, Metal-insulator-semiconductor structure, Capacitance-voltage
