Abstract: The present invention relates to an electrification unit of an electrostatic precipitator, and more particularly, to an electrification unit having a discharge electrode, which connects a plurality of unit discharge electrodes in a row by means of a connecting terminal, and a groove-shaped fixing structure provided in a casing so that the connecting terminal and a connection part of the unit discharge electrode can be simply fixedly inserted into the corresponding groove, thereby providing excellent assemblability and electrical insulation and improving manufacturability and electrical stability.

Abstract: Provided are a two-terminal switching device having a bidirectional switching property, and a resistive memory cross-point array including the same. The two-terminal switching device includes a first electrode. A first tunneling barrier layer is disposed on the first electrode. An oxide semiconductor layer is disposed on the first tunneling barrier layer. A second tunneling barrier layer is disposed on the oxide semiconductor layer. A second electrode is disposed on the second tunneling barrier layer.

Abstract: A resistive memory device includes a stack of two layers of variable resistance material and top, middle, and bottom electrodes, the stack symmetrical in composition about the middle electrode.
