      Micro-electro-mechanical switches offer many benefits over solid-state switches. Due to the physical limitations of power transistors, high-power switches based on micro-electro-mechanical-systems (MEMS) technology have been attracting more attention. However, reliability and lifetime of the contact are among the challenges of MEMS contact switches, especially for high-power applications. Dahmardeh et al. (pp. 631–638) use vertically aligned carbon nanotubes, so called CNT forests, as the contact material for MEMS switches to reveal very promising performance characteristics. A micromachined shape-memory-alloy (SMA) actuator is integrated with a CNT-forest contact, showing device operation with input powers over 5 W. Long-term operation for over 1 × 106 switching cycles is demonstrated. Combining CNTs and SMAs potentially enables a robust switching device desirable for high-power, DC/low-frequency applications. The cover image symbolically illustrates the approach taken by the researchers towards realizing reliable MEMS switches through a carbon nanotube “path”.

      Back Cover: Defect generation, advanced crystallization, and characterization methods for high-quality solar-cell silicon (Phys. Status Solidi A 4/2013)

      Marisa Di Sabatino and Gaute Stokkan

      Version of Record online: 4 APR 2013 | DOI: 10.1002/pssa.201390010

      Thumbnail image of graphical abstract

      Silicon is the dominant material for production of solar cells. In this Feature Article by Di Sabatino and Stokkan (pp. 641–648), the authors review some of the latest work carried out at Norwegian University of Science and Technology (NTNU) to understand the role of defects and impurities on materials properties. Specifically they report on some of the work done on defects, crystallization and characterization. It has been demonstrated that defects and impurities, often arising during the silicon ingot production and, due to the presence of impurity sources throughout the silicon solar cell value chain, have a detrimental effect on device performances. Crystallization is the first step in the solar cell value chain. During crystallization, crystal defects, such as grain boundaries and dislocations, develop and impurities, such as dopants and metals, distribute. By controlling the process we can also control the defect formation and impurity segregation. The micrograph shows typical dislocation clusters in a multicrystalline silicon wafer.

      Masoud Dahmardeh, Mohamed Sultan Mohamed Ali, Tanveer Saleh, Tee Min Hian, Mehran Vahdani Moghaddam, Alireza Nojeh and Kenichi Takahata

      Version of Record online: 19 FEB 2013 | DOI: 10.1002/pssa.201228678

      Thumbnail image of graphical abstract

      A high-power micro-electro-mechanical switch is realized using a forest of vertically aligned carbon nanotubes (CNT) as contact material and a shape-memory-alloy (SMA) actuator. Large-force actuation of SMA enables vastly distributed contacts between the forest and the copper electrode, achieving low contact resistance and high current conduction. The contact material also shows varistor-like behavior. Long-term switching for over one-million cycles is demonstrated.
