通过在有机阻抗开关器件的电流-电压特性中引入非线性行为，提高了作为交叉点矩阵存储元件的有机阻抗开关器件的可寻址性。这是通过在玫瑰红（RB）钠盐的开关层上添加酞菁铜（II）（CuPc）的半导体层来实现的。来自矩阵中未寻址单元的漏电流减少了17倍，从而提高了信号背景比，降低了驱动器电流，并限制了沿寻址线的沿着电位降。RB开关器件的矩阵尺寸，使用有机导体，预计将增加32倍时，使用额外的CuPc层。
The addressability of organic impedance switch devices as the memory elements of cross-point matrices is improved by introducing nonlinear behavior in their current-voltage characteristics. This is realized by adding a semiconducting layer of copper (II) phthalocyanine (CuPc) on top of the switch layer of Rose Bengal (RB) sodium salt. Leakage currents from unaddressed cells in a matrix are reduced by a factor of 17; thus improving the signal-to-background ratio, reducing driver currents and limiting the potential drop along the addressing lines. The matrix size of RB switch devices, using organic conductors, is predicted to be increased by 32 times when using the additional CuPc layer.
