Background
-AFOSR Supports basic research – sole manager of AF basic research (inc.
London, Tokyo, Santiago Offices)
-Small, light, and low-power-consumption communications, computing and
sensing components are critical to aerospace systems
-In 2012 it was observed that no US funding agency has programs on
heterostructures of 2D layers
-AFOSR-NSF joint workshop on 2D Materials and Devices Beyond Graphene
held 30-31 May 2012 with ~100 attendees
- AFOSR BRI on 2D was briefed on 6 Aug 2012 & funds were made available for
FY14 (1 Oct 2013) (main thrust 2D heterostructures)
-AFOSR BRI coordinated with NSF Emerging Frontiers in Research and
Innovation (EFRI – 2DARE) (EFRI-2014/2015)
-AFOSR BRI grants in place late 2014

Example BRI Project:
2D Materials & Devices Beyond Graphene
Project Awarded: FA9550-14-1-0277, start 9/15/14
Title: 2D Heterostructures for Integrated Nano
Optoelectronics
Prof Xiaodong Xu, Univ of Washington lead
Website: http://depts.washington.edu/muri14/optoelectronics/
Four Publication 2014:
Strong light–matter coupling in two-dimensional atomic crystals.
Ultra-low threshold monolayer semiconductor nanocavity lasers.
Single Quantum Emitters in Monolayer Semiconductors.
Two-dimensional material nanophotonics.
- Cavity quantum electrodynamics dictates that
the spontaneous emission rate of a nanoscale
light emitter can be significantly enhanced
through engineering its electromagnetic environment by a photonic nanocavity in Purcell regime.
- Observed such Purcell effect by integrating a
monolayer semiconductor WSe2 with a photonic
crystal cavity (PhCC)
Photonic nanocavity in Purcell regime 5
