Title: "2D Materials for Next-Generation Microelectronics: From CMOS Devices To Monolithic 3D 
        Integrated Systems"

Date: Friday, 3rd July 2026 - Time: 4 PM

Hi-Tea & Coffee: 5 PM

Venue: CeNSE Seminar Hall

Abstract:

In this talk, I will provide an overview of my research efforts aimed at advancing two-dimensional 
(2D) electronics from fundamental device innovation to fully integrated computing and sensing systems. 
I will discuss the development of wafer-scale, high-performance p-type WSe2 transistors enabled by 
controlled nitric-oxide doping, which addresses a long-standing limitation in achieving 
complementary 2D CMOS logic. I will then highlight our demonstration of a complementary 2D 
one-instruction-set computer constructed from large-area MoS2 and WSe2 devices, illustrating how 
2D materials can support scalable and energy-efficient computation. The talk will also explore 
monolithic three-dimensional integration platforms that bring together graphene chemisensors, 
MoS2 memtransistors, and dense interlayer vias within nanoscale vertical proximity. Finally, 
I will describe a self-powered 3D integrated circuit that combines 2D CMOS logic, graphene 
sensing modules, and silicon photovoltaics to enable autonomous, near-sensor intelligence.


Biography:
Subir earned his bachelor’s degree in Electronics and Communication Engineering from the 
Heritage Institute of Technology, Kolkata, in 2018, and his master’s degree in Electron 
Devices from Jadavpur University in 2021, where he worked on atomistic simulations of 2D materials. 
He then served as a VLSI Engineer at DxCorr Design Technology before beginning his Ph.D. at Penn 
State University in 2022. His research focuses on high-performance 2D transistors, large-scale 
2D integrated circuits, and monolithic 3D integration that unifies sensing, computation, and 
energy harvesting, along with interests in neuromorphic and strain engineered 2D systems. 
He has also won best paper awards in DRC 2025 and ICEE 2025.
