TL;DR: The approach employs a process of stable heating at a high temperature and then cooling down naturally to room temperature with the nanowire growth occurred effectively during the naturally cooling step, resulting in high material quality nanowires.
Abstract: We report on a simple but powerful approach to grow high material quality InSb and GaSb nanowires in a commonly used tube furnace setup. The approach employs a process of stable heating at a high temperature and then cooling down naturally to room temperature with the nanowire growth occurred effectively during the naturally cooling step. As-grown nanowires are analyzed using a scanning electron microscope and a transmission electron microscope equipped with an energy-dispersive X-ray spectroscopy setup. It is shown that the grown nanowires are several micrometers in lengths and are zincblende InSb and GaSb crystals. The FET devices are also fabricated with the grown nanowires and investigated. It is shown that the grown nanowires show good, desired electrical properties and should have potential applications in the future nanoelectronics and infrared optoelectronics.

TL;DR: In this article, a Type II InAs/GaSb superlattice mid-infrared photon detector was demonstrated with a noise equivalent temperature of 10mK at 77k and a detectivity of 3x10 13 cm.
Abstract: Recent efforts have been paid to elevate the operating temperature of Type II InAs/GaSb superlattice Mid Infrared photon detectors. Optimized growth parameters and interface engineering technique enable high quality material with a quantum efficiency above 50%. Intensive study on device architecture and doping profile has resulted in almost one order of magnitude of improvement to the electrical performance and lifted up the 300K-background BLIP operation temperature to 166K. At 77K, the ~4.2 m cut-off devices exhibit a differential reP sistance area product in excess of the measurement system limit (10 6 Ohm.cm 2 ) and a detectivity of 3x10 13 cm.Hz 1/2 /W. High quality focal plane arrays were demonstrated with a noise equivalent temperature of 10mK at 77K. Uncooled camera is capable to capture hot objects such as soldering iron. Keywords: Type II superlattice, InAs/GaS b, M-structure, photodetector s, MWIR, focal plane arrays. INTRODUCTION: TYPE II ANTIMONIDE BASED SUPERLATTICES
