Abstract: Disclosed are a growth structure for a strained channel, and a strained channel using the same and a method of manufacturing a device using the same. The growth structure for a strained channel includes a support substrate, a strain-relaxed buffer (SRB) layer disposed on a support substrate, a base growth layer grown to have one composition on the SRB layer, and a strained channel layer grown to have another composition on the base growth layer. The strained channel layer may include at least one of a tensile-strained channel layer or a compressively strained channel layer.

Abstract: Disclosed are an ultra-high sensitivity target signal detection method based on analysis of a noise signal of a sensor using deep learning based anomaly detection and a system using the same. More particularly, disclosed are a method and apparatus for receiving a noise signal from a sensor and inputting data to an artificial neural network trained with a normal noise signal to determine whether or not a target signal is present. The target signal detection method is capable of detecting a target signal having a very low concentration that can be detected by a conventional sensor, whereby the target signal detection method is useful in developing an ultra-high sensitivity sensor.
