Ligand‐Mediated Surface Carrier Modulation in Perovskite Nanocrystals for Charge‐Symmetric LEDs
Advanced Materials, EarlyView.A hydrolysis‐assisted ligand exchange strategy enables surface carrier modulation of perovskite nanocrystals using a multifunctional π‐conjugated ligand. This molecular surface design achieves charge balance and recombination‐zone symmetry in light‐emitting diodes (LEDs), which leads to high‐efficiency perovskite LEDs and establishes a general platform

A closed-loop digitally controlled MEMS gyroscope with unconstrained Sigma-Delta force-feedback [PDF]
, 2009 In this paper, we describe the system architecture and prototype measurements of a MEMS gyroscope system with a resolution of 0.025 degrees/s/root Hz. The architecture makes extensive use of control loops, which are mostly in the digital domain.
