Abstract: A battery defect detection apparatus according to an embodiment disclosed herein includes: a communication module; a processor; and a memory configured to store a first artificial intelligence model, a second artificial intelligence model, and instructions, in which the processor is configured to execute the instructions by the battery defect detection apparatus; to perform operations including: obtaining an image of a subject product by using the communication module, inputting the image of the subject product to the first artificial intelligence model to classify the subject product, and inputting the image of the subject product to the second artificial intelligence model to determine whether the image of the subject product corresponds to first data for classifying the subject product as normal among learning data of the first artificial intelligence model, when the subject product is classified as normal.

Abstract: Provided are a contact fabric using a heterostructure of metal/semiconductor nanorods and a method of manufacturing the same. An ohmic contact fabric having a low contact resistance or a Schottky contact fabric having a rectification characteristic is formed by selectively depositing metal of nano-sizes onto predetermined portions of zinc oxide/semiconductor nanorods and controlling the work function of the deposited metal and the interfacial characteristics of metal/zinc oxide. The contact fabric can be applied to various nano-sized electronic devices, including Schottky diodes, optical devices, and arrays thereof.

Abstract: The present invention relates to a nano-material/phosphor hetero-structure including a phosphor coated on a one-dimensional nano-material.

Abstract: A heterojunction structure composed of a nitride semiconductor thin film and nanostructures epitaxially grown thereon exhibits high luminescence efficiency property due to facilitated tunneling of electrons through the nano-sized junction, and thus can be advantageously used in light emitting devices.
