A multilayered structure consisting of ferroelectric Pb（Zr, Ti）Oa （PZT） film is deposited by sputtering on the crystalline silicon p-n junction without any buffer layer. The photovoltaic output of the p-n junction is greatly enhanced due to the usage of In2Oa：Sn（ITO）/PZT as top surface passivation layers. The short circuit current and photoelectric conversion emciency of the p-n junction with ITO/PZT ferroelectric films increase about four and six times, respectively, compared with those without any passivation layers. Improvement in the passivated device is mainly attributed to the builtqn feld at the ITO/PZT interface.

Casimir force and residual stresses actually appear in over-layers or films simultaneously. The study of the behaviour of micro- and nano-electromechanical systems in the presence of Casimir force and residual stress is of significance to the design of the relevant devices. We derive analytical expressions of the deflection of a bridge-shaped device under the mutual actions of Casimir force and residual stress in films. It is shown that the tensile residual stress enhances wavy behaviour of the deflection, while the compressive residual stress increases the deflection value and reduces the wavy behaviour.

In this paper, disturbed sparse linear equations over the 0-1 finite field are considered. Due to the special structure of the problem, the standard alternating coordinate method can be implemented in such a way to yield a fast and efficient algorithm. Our alternating coordinate algorithm makes use of the sparsity of the coefficient matrix and the current residuals of the equations. Some hybrid techniques such as random restarts and genetic crossovers are also applied to improve our algorithm.
