During the last decade, SSL (Solid-State Lighting) based on components like LEDs, OLEDs, and LDs, have challenged conventional technologies. LEDs have turned into a game changer, beating conventional technologies in all aspects. It is therefore anticipated that in the short term, all electric lighting will be based on SSLs. Artificial light production absorbs around 2,900 TWh per year, corresponding to 16.5% of the world’s electricity annual production. Historically speaking, the past century’s research and development has focused on energy efficiency enhancement. Today, we are witnessing a transition from conventional “analog” lighting technologies to “digital” lighting. Intelligent lighting will become the backbone of smart homes and smart cities. This way, lighting will become the heart of the “Internet of Things”. Switching to smart human-centric lighting will drive both “application efficiency” and quality of light. This means that the next-gen lighting systems should provide the “right light” with the best efficiency and quality, when and where it is needed.

The Electron Devices Society Santa Clara Valley/San Francisco joint Chapter is hosting Prof. Eric Pop. The title of the lecture is ‘What Are 2D Materials Good For?’ When: Friday, July 28, 2023 – 12 Noon to 1 pm (PDT) Where: This is an online event and attendees can participate via Zoom. Registration Link: (https://bit.ly/42HxqXv) Contact: hiuyung.wong at ieee.org Speaker: Prof. Eric Pop Abstract: This talk will present my (biased!) perspective of what two-dimensional (2D) materials could be good for. For example, they could be good for applications where their ultrathin nature gives them distinct advantages, such as flexible electronics or light-weight solar cells . They may not be good where conventional materials work sufficiently well, like transistors thicker than a few nanometers. I will focus on 2D materials for 3D heterogeneous integration of electronics, which presents major advantages for energy-efficient computing . Here, 2D materials could be monolayer transistors with ultralow leakage (due to larger band gaps than silicon), used to access high-density memory . Recent results from our group and others have shown monolayer transistors with good performance, which cannot be achieved with sub-nanometer thin conventional semiconductors, and the 2D performance could be further boosted by strain . I will also describe some unconventional applications, using 2D materials as thermal insulators , heat spreaders , and thermal transistors . These could enable control of heat in “thermal circuits” analogous with electrical circuits. Combined, these studies reveal fundamental limits and some unusual applications of 2D materials, which take advantage of their unique properties. Refs: A. Daus et al., Nat. Elec. 4, 495 (2021). K.
