Re-imagining electronic materials
engineering emergent ferroelectric order and negative electronic properties in otherwise ordinary dielectrics
Re-imagining the transistor
from high-k dielectric to negative-k ferroelectric gate stacks
for ultralow power transistor operation
Re-imagining the capacitor
from electrochemical to electrostatic energy storage
for ultrahigh-density ultrafast-charging capacitors
Challenge: Novel electronic phenomena often found in "exotic" material systems not compatible with today's microelectronics, preventing lab-to-fab translation
Solution: Manipulate crystal symmetry to design next-generation electronic materials with breakthrough (and often negative) properties in CMOS-compatible materials already in today's microelectronics
