Planar optical waveguides in 
-BaB2O4 produced by oxygen ion implantation at low doses
The planar waveguides have been fabricated in z-cut -BaB2O4 crystal by 2.2 MeV O+ ion implantation at doses ranging from 5×1012 to 5×1014 ions/cm2 at room temperature...

Tuning of emission color for blue dendrimer blend light-emitting diodes
We demonstrate efficient tunable blue electroluminescence from blends of two solution-processible light-emitting dendrimers. These materials can be blended to form optical quality thin films with no p...

Fabrication techniques usually applied to microelectromechanical systems (MEMS) are used to reduce the size and operating power of the core physics assembly of an atomic clock. With a volume of 9.5 mm3, a fractional frequency instability of 2.5×10–10 at 1 s of integration, and dissipating less than 75 mW of power, the device has the potential to bring atomically precise timing to hand-held, battery-operated devices. In addition, the design and fabrication process allows for wafer-level assembly of the structures, enabling low-cost mass-production of thousands of identical units with the same process sequence, and easy integration with other electronics.
