ABSTRACTInSb thin films on oxidized Si wafers have been recrystallized using a strip heater to generate and scan a narrow molten zone across the film. Grains up to 3 × 10 mm have been produced. Crystallization proceeds in a faceted cellular fashion, the excess solute (Sb) being rejected into subboundaries which often lie along low-index crystallographic directions. A InSb-Sb eutectic structure forms at the subboundaries. The width of the single-crystal InSb between subboundaries is approximately 75 μm. The techniques of planar constriction and subboundary entrainment have been extended to InSb for the selection of single grains and the orelocation of subboundaries. This technology of producing InSb thin films on oxidized Si substrates max, be extendable to other III-V materials, and could lead to novel device structures through the integration of Si and III-V compound devices on the same substrate.

Nanopore Sensors

Microfluidic system, as a kind of miniature integrated operating platform, has been applied to solid-state nanopore sensors after many years of experimental study. In the process of introducing microfluidic into solid-state nanopore sensors, many novel device structures are designed due to the abundance of analytes and the diversity of detection methods. Here we review the fundamental setup of nanopore-based microfluidic systems and the developments and advancements that have been taking place in the field. The microfluidic systems with a multichannel strategy to elevate the throughput and efficiency of nanopore sensors are then presented. Multifunctional detection represented by optical-electrical detection, which is realized by microfluidic integration, is also described. A high integration microfluidic system with nanopore is further discussed, which shows the prototype of commercialization.
