Addressing Grand Challenges in Energy Consumption-Storage-Generation for Sustainable Microelectronics

We aim to address energy grand challenges - particularly the exponential rise in global energy consumption from computing, artifical intelligence (AI) and Internet-of-Things (IoT) devices

from a microelectronics perspective, leveraging collective electronic phenomena, engineered at the unit cell level. 

Towards making an impact on technology, our research focuses on manipulating novel-yet-simple CMOS materials towards lab-to-fab translation of electronic devices that demonstrate unprecedented performance.

More Moore

Energy demand from computing has been increasing much faster than the world's energy production; at this rate, in 20 years, computing will require more electricity than the world can generate; novel energy-efficient computing paradigms are required 

More than Moore

The exponential rise of IoT smart devices (approaching 1 trillion) and energy/heat dissipation in modern microchips demand innovations in self-powered nanotechnologies - spanning rechargeable energy storage, energy harvesting, & power delivery - integrated on-chip

Designing Emergent (Negative) Electronic Phenomena in Atomically-Engineered Composite Materials & Integration into CMOS Technology

We are an interdisciplinary group at the intersection of materials science, condensed matter physics, and nanoelectronics to realize the applied impact of electronic metamaterials.

Rather than exploring the entire periodic table, we focus on manipulating simple materials in today's mass production microelectronics  to accelerate the technological adoption of novel electronic devices.

Atoms to Devices

Materials-by-Design Synthesis

To stabilize emergent phenomena beyond the standard unit cell, we utilize Atomic Layer Deposition (ALD) to manufacture hierarchical “super-cells”. ALD, used in today's microelectronics, deposits atomically-precise films across large-area substrates to enable large-scale integration and facilitate Lab-to-Fab translation.

Thin Film Characterization

To understand the microscopic origins underlying electronic metamaterials, we employ (i) synchrotron x-rays (diffraction, spectroscopy, microscopy), (ii) microscopy (electron, scanning probe), and (iii) transport (ultrafast, cryogenic, etc) at National Laboratories, MIT facilities, and in-house setups.

Electronic Devices

To realize enhanced performance derived from emergent symmetry-broken phenomena, we integrate electronic metamaterials into relevant device structures (e.g. capacitors, transistors)  fabricated (i) in-house at MIT.nano (ii) next-door at MIT Lincoln Laboratory and (iii) in collaboration with semiconductor industries.
