Hard way or hardware? Taking the heat out of AI
Jayakrishnan, Ampattu R.; Hellenbrand, Markus; Dixon, Sebastian; Mehonic, Adnan; Silva, José Pedro Basto; MacManus-Driscoll, Judith L.The flurry of news worldwide surrounding the launch of DeepSeek’s artificial intelligence (AI) tool, operating at ∼5% of OpenAI’s GPT models, has drawn significant attention to global competitiveness in the AI field. Greater efficiency in software design to lower costs is of clear benefit to AI customers. It is also, however, critical to acknowledge the urgent need to sustain the otherwise continuous growth of ...
Ultra-sensitive, self-powered, CMOS-compatible near-infrared photodetectors for...
Silva, Nuno E.; Jayakrishnan, Ampattu R.; Kaim, Adrian; Gwozdz, Katarzyna; Domingues, Leonardo; Kim, J. S.; Istrate, Marian C.; Ghica, CorneliuSelf-powered near-infrared (NIR) photodetectors are essential for surveillance systems, sensing in IoT electronics, facial recognition, health monitoring, optical communication networks, night vision, and biomedical imaging. However, silicon commercial detectors need external power to operate and cooling to suppress large dark currents. This work demonstrates a new class of CMOS-compatible self-powered NIR phot...
The benefits of incorporating lead-free ferroelectric materials in high energy ...
Jayakrishnan, Ampattu R.; Isfahani, Vahideh B.; Nair, Surya Kiran P.; Sekhar, Koppole C.; Marques, L.; Pereira, Mario; MacManus-Driscoll, Judith L.Demand for energy storage is increasing day by day and developing a pollution free environment necessitates new battery technologies. However, the existing energy storage technologies like lithium (Li)-ion batteries cannot fulfil the future needs alone. In this regard, Li-free batteries such as sodium (Na), potassium (K), zinc (Zn) and magnesium (Mg) ion batteries have attracted significant attention due to the...
Inorganic ferroelectric thin films and their composites for flexible electronic...
Jayakrishnan, Ampattu R.; Kumar, Anuj; Sahaha, D.; John, Rosmin; Sudheesh, Meera; Puli, Venkata Sreenivas; Silva, José Pedro Basto; Gomes, M. J. M.Scientific researches are at the inception of flexible energy devices and ferroelectric (FE) materials mark their signature in the process. Particularly, devices based on inorganic FE (IFE) materials find a remarkable role in the flexible energy devices such as energy harvesters, infrared (IR) sensors, and energy storage capacitors because the latest technologies are particularly concentrated on self-powered fl...
Pyroelectric nanogenerators in energy technology
Jayakrishnan, Ampattu R.; Silva, José Pedro Basto; Sathish, Sugumaran; Kamakshi, Koppole; Sekhar, Koppole C.[Excerpt] International crisis such as global warming, environmental pollution, and e-waste significantly increased the demand of electronic devices powered by renewable and sustainable energy sources [1, 2]. It is known that batteries are key renewable energy sources for powering electronic systems, which suffer from drawbacks like environmental issues, limited life-time, weight, and periodic maintenance or re...
