We report a bipolar $SiO_{2}$-based selector with threshold switching and self-compliance characteristics. The device turns ON under applied voltage of about $\pm 0.6{V}$, and turns OFF when the applied voltage drops below $\pm 0.04{V}$. Engineering of the copper (Cu) supply film is implemented by alloying Cu with $Ge_{2}Sb_{2}Te_{5}(GST)$. This enables appropriate modulation of the Cu concentration and migration in the active $SiO_{2}$ film, which is responsible for the reliable self-compliance bipolar threshold switching.

One new organic-inorganic hybrid materials of complex Ag2ClO5N5C28H22 (1) was synthesized by evaporation methods using 2-Chlorobenzeneacetic acid(2-CBAA), 4,4'-dipyridyl (4,4'-bipy), and AgNO3. And the complex was characterized by elemental analysis, FT-IR, thermogravimetrie analysis(TGA), XRD, X-ray single-crystal structure analysis and fluorescence properties have been studied. As a result, complex 1 are one-dimensional structure. Among others, Ag(I) ion is surrounded by two nitrogen atoms from two bipy ligands form an infinite chain, and adjacent Ag-bipy chains produce "rungs" of a ladder by silver ions contacts. Complex 1 emits the intensely luminescence with the fluorescence of 486 nm in a solid state at room temperature. CCDC
