The invention relates to a metal lithium negative electrode with a dual-layer structure. The metal lithium negative electrode comprises a metal lithium layer at a bottom layer and a surface cover layer at an upper layer. In the metal lithium negative electrode, a surface layer structure on the surface can be used for controlling distribution of lithium ions on the surface of the negative electrode, the lithium ions are prevented from being gathered in time and space, and the uniform distribution of the lithium ions on the surface of the negative electrode is achieved, so that dendritic crystal is prevented.

A reflective spatial light modulator device features two pairs of electrodes formed on different metallization layers. Elevation of the upper electrode pair reduces its distance from the overlying reflecting surface, thereby requiring a smaller applied voltage to generate an equivalent electrostatic attractive force for altering or maintaining physical orientation of the reflecting surface relative to incident light. In one embodiment, the reduced distance between the electrode and reflecting surface allows operation at lower voltages, reducing the possibility of breakdown and avoiding the need for complex device designs to eliminate such breakdown. In another embodiment, the reduced distance between the electrode and the reflecting surface allows the use of stiffer hinges for the reflecting surface, thereby increasing the speed of device operation. Other embodiments can employ both reduced voltage operation and the use of stiffer hinge structures.
