OCTOBER 2024 I DESIGN007 MAGAZINE 71 Applications such as VR concerts or sporting events allow viewers to experience live events from multiple angles and perspectives in real time. 5. Theater and Cinema Projection 8K and 16K projection systems: Cinema projection systems are evolving to support ultra-high-definition content with resolu- tions up to 16K. UHDI enables the projection of incredibly detailed imagery on massive screens, ensuring that viewers in theaters experience crystal-clear images even at extreme sizes. HDMI 2.1, DisplayPort 2.0, and fiber optic connections support the band- width needed for such high-resolution projec- tion systems. Laser and LED projectors: Emerging laser and LED projection technologies can sup- port extremely high resolutions with higher contrast ratios and wider color gamuts. UHD interconnects are crucial for delivering the 8K or higher video signals to these projectors with minimal latency and maximum quality. Bleeding-edge UHDI applications in the entertainment industry are reshaping how content is produced, distributed, and con- sumed. e ability to handle ultra-high-resolu- tion video and audio, alongside real-time data processing, has led to richer, more immersive experiences in gaming, film, live events, and beyond. As technology continues to evolve, ultra high-definition interconnect cables will remain critical in pushing the entertainment industry's boundaries.

Imagine a thin film, just nanometers thick, that could store gigabytes of data—enough for movies, video games, and videos. This is the exciting poten- tial of ferroelectric materials for memory storage. These materials have a unique arrangement of ions, resulting in two distinct polarization states analo- gous to 0 and 1 in binary code, which can be used for digital memory storage. These states are stable, meaning they can 'remember' data without power, and can be switched efficiently by applying a small electric field. This property makes them extremely energy-efficient and capable of fast read and write speeds. However, some well-known ferroelectric materials, such as Pb(Zr,Ti)O 3 (PZT), and SrBi 2 Ta 2 O 9 , degrade and lose their polarization when exposed to heat treatment with hydrogen during fabrication. In a study published in the journal Applied Phys- ics Letters, a research team led by Assistant Profes- sor Kazuki Okamoto and Hiroshi Funakubo at Tokyo Institute of Technology (Tokyo Tech), in collaboration with Canon ANELVA Corporation and Japan Syn- chrotron Radiation Research Institute (JASRI), has shown that aluminum scandium nitride (AlScN) fer- roelectric films remain stable and maintain their fer- roelectric properties at temperatures up to 600°C. "Our results attest to the high stability of the fer- roelectricity of the films subjected to heat treatment in hydrogen-included atmosphere, regardless of the electrode material. This is a highly promising result for next-generation ferroelectric memory devices and offers more processing options," says Funakubo.
