Ningxin Li et al. from Georgia State University have published a new article titled "Van der Waals Semiconductor Empowered Vertical Color Sensor" in ACS Nano. Abstract Biomimetic artificial vision is receiving significant attention nowadays, particularly for the development of neuromorphic electronic devices, artificial intelligence, and microrobotics. Nevertheless, color recognition, the most critical vision function, is missed in the current research due to the difficulty of downscaling of the prevailing color sensing devices. Conventional color sensors typically adopt a lateral color sensing channel layout and consume a large amount of physical space, whereas compact designs suffer from an unsatisfactory color detection accuracy. In this work, we report a van der Waals semiconductor-empowered vertical color sensing structure with the emphasis on compact device profile and precise color recognition capability. More attractive, we endow color sensor hardware with the functi...

Samsung is the world’s second-biggest mobile camera sensor maker, and its sensors are used by almost every smartphone brand. Over the past couple of years, the South Korean firm has launched various big-sized camera sensors, including the ISOCELL GN1 and the ISOCELL GN2. This year, it has made one more giant ISOCELL camera sensor. The company has developed the ISOCELL GNV camera sensor, and it will be used in a Vivo smartphone. It is being reported that the ISOCELL GNV is custom-made for Vivo phones, and it has a size of 1/1.3-inch. It is most likely a 50MP sensor, similar to the ISOCELL GN1, ISOCELL GN2, and the ISOCELL GN5. It will act as the Vivo X80 Pro+’s primary camera and features a gimbal-like OIS system. The ISOCELL GNV is likely a slightly modified version of Samsung’s ISOCELL GN1. The Vivo smartphone has three other cameras, including a 48MP/50MP ultrawide camera (Sony IMX sensor), a 12MP telephoto camera with 2x optical zoom and OIS, and an 8MP telephoto camera with 5x opti...

Krister Shalm of National Institute of Standards and Technologies presented a tutorial: Single-photon detectors at the 2013 QCrypt Conference in August. http://2013.qcrypt.net This is from a while back but an excellent educational resource nevertheless! The video is roughly 90-minutes long but has several gaps that can be skipped ahead. Or play it at >1x speed! Full video here: https://www.youtube.com/watch?v=Vt84rSJa7VI&t=541s

A research group from the Indian Institute of Science has published a perspective article titled "The road ahead for ultrawide bandgap solar-blind UV photodetectors" in the Journal of Applied Physics. Abstract: This perspective seeks to understand and assess why ultrawide bandgap (UWBG) semiconductor-based deep-UV photodetectors have not yet found any noticeable presence in real-world applications despite riding on more than two decades of extensive materials and devices’ research. Keeping the discussion confined to photodetectors based on epitaxial AlGaN and Ga2O3, a broad assessment of the device performance in terms of its various parameters is done vis-à-vis the dependence on the material quality. We introduce a new comprehensive figure of merit (CFOM) to benchmark photodetectors by accounting for their three most critical performance parameters, i.e., gain, noise, and bandwidth. We infer from CFOM that purely from the point of view of device performance, AlGaN detectors ...
