Abstract:
METHOD OF FORMING OXIDE-BASED NANO-STRUCTURED MATERIAL Provided is a method of forming an oxide-based nano-structured material including growing a nano- structured material using a nano-nucleus having the same composition as the desired oxide-based nano- structured material. A solution is coated on a substrate, the solution including: an organic precursor containing M which is a transition metal or a semi metal; and an organic solvent in which the organic precursor is dissolved. A nano-nucleus having a composition of MxOy is formed on the substrate by annealing the substrate. A nano-structured material having a composition of MxOy is formed by growing the nano-nucleus while supplying a reaction precursor containing M into the nano-nucleus, and the nano- structured material is annealed.
Abstract:
A method of forming an oxide-based nano-structured material by growing a nano-structured material using a nano-nucleus having the same composition as the desired oxide-based nano-structured material. A solution is coated on a substrate by dipping, spin or spray coating. The solution includes an organic precursor containing a transition metal or a semi metal and an organic solvent in which the organic precursor is dissolved. A metal oxide nano-nucleus is then formed on the substrate by annealing the substrate. A metal oxide nano-structured material is formed by growing the nano-nucleus while supplying a reaction precursor containing the same metal as the formed oxide into the nano-nucleus. Methods used for this step include PVD, CVD and sol gel processes. The nano-structured material is finally annealed. The structure can be used in an electronic device such as a diode, a display, FET, SET or a battery.
Abstract:
PURPOSE: An RFID system using human body communication is provided to remarkably reducing the power consumption of a reader and a tag. CONSTITUTION: A first electrode pad receives a signal of a reader(320) transmitted from a body and outputs an output signal to the body. A modulator and a demodulator modulate the output signal of a tag(310) and demodulate the signal of the reader. A digital controller performs the reading and writing operations by responding to the modulated signal of the reader. A coil is connected between the first electrode pad and the second electrode pad. When the tag is operated in a first operation mode, a mode selector connects the second electrode pad with a rectifier. In case that the tag is operated in a second operation mode the mode selector releases the connection between the second electrode pad and the rectifier.
