Deep Jariwala is an Associate Professor and the Peter & Susanne Armstrong Distinguished Scholar in the Electrical and Systems Engineering as well as Materials Science and Engineering at the University of Pennsylvania (Penn). Deep completed his undergraduate degree in Metallurgical Engineering from the Indian Institute of Technology in Varanasi and his Ph.D. in Materials Science and Engineering at Northwestern University. Deep was a Resnick Prize Postdoctoral Fellow at Caltech before joining Penn to start his own research group. His research interests broadly lie at the intersection of new materials, surface science and solid-state devices for computing, opto-electronics and energy harvesting applications in addition to the development of correlated and functional imaging techniques. Deep’s research has been widely recognized with several awards from professional societies, funding bodies, industries as well as private foundations, the most notable ones being the Optica Adolph Lomb Medal, the Bell Labs Prize, the AVS Peter Mark Memorial Award, IEEE Photonics Society Young Investigator Award, IEEE Nanotechnology Council Young Investigator Award, IUPAP Early Career Scientist Prize in Semiconductors, the SPIE Early career achievement award and the Alfred P. Sloan Fellowship. He has published over 150 journal papers with more than 22000 citations and holds several patents. He serves as the Associate Editor for Nano Letters (ACS) and has been appointed as a Distinguished Lecturer for the IEEE Nanotechnology Council for 2025.

Modern computing faces significant challenges in the post-Moore's Law era, particularly as applications shift from arithmetic-centric to data-centric paradigms driven by artificial intelligence and ubiquitous connectivity. Silicon will likely remain dominant for the foreseeable future, but there's a pressing need for innovative materials and device architectures to complement silicon and enable more efficient, powerful, and versatile computing systems for both conventional and extreme environments.

In this talk, I will first discuss our research on two-dimensional (2D) chalcogenide semiconductors for next-generation electronics. These materials exhibit remarkable properties when integrated with silicon to create low-power quantum-mechanical tunneling dominated field effect transistors, particularly using In-Se based semiconductors. I will highlight our achievements in phase-pure epitaxial thin-film growth at wafer scales, compatible with back-end-of-line processing in silicon fabs.

I will then present our work on integrating 2D materials with emerging ferroelectric nitride materials for advanced memory applications. Specifically, I will focus on how integrating 2D semiconductors with wurtzite structure ferroelectric nitrides, particularly aluminum scandium nitride (AlScN), creates high-performance ferroelectric field-effect transistors (FE-FETs). Our latest results demonstrate scaling of 2D/AlScN FE-FETs to achieve ultra-high carrier and current densities in ferroelectrically gated MoS₂. This section will also cover ferroelectric diode (FeD) memory devices with multi-bit operation and compute-in-memory capabilities. The exceptional temperature stability of AlScN FeDs, with stable operation up to 600°C and data retention up to 1000°C when integrated with SiC, as well as down to -261 °C makes these devices uniquely suited for extreme environment computing applications.

Next, I will explore how strong light-matter coupling in excitonic 2D semiconductors enables novel photonic devices and quantum light sources. Transition metal dichalcogenides (TMDCs) of molybdenum and tungsten, with their visible spectrum bandgaps and strong excitonic absorption, serve as excellent platforms for investigating strong light-matter interactions and the formation of hybrid states. I will give a glimpse into our recent work in this area using TMDCs and metal organic chalcogenolates for achieving strong to ultra-strong coupling of photons with excitons in these 2D semiconductors and its applications in optoelectronic devices including quantum light sources.

I will conclude by presenting a vision for how novel materials can lead the way for novel devices which in turn could enable novel computing paradigms including quantum computing as well as cryogenic classical computing using quantum phases of matter.
