Abstract: Briefly, in accordance with one or more embodiments, an electrostatic acoustic transducer comprises a substrate comprising a first material to function as a first electrode, a dielectric layer coupled with the first material, wherein the dielectric layer has one or more cavities formed therein, and a membrane coupled with the dielectric layer to cover one or more of the one or more cavities and to function as a second electrode. The electrostatic acoustic transducer generates an acoustic wave in response to an electrical signal applied between the first electrode and the second electrode, wherein the applied electrical signal comprises a direct-current (dc) bias voltage and one or more time-varying electrical signals.

Abstract: An optical structure can include a nanocrystal on a surface of an optical waveguide in a manner to couple the nanocrystal to the optical field of light propagating through the optical waveguide to generate an emission from the nanocrystal. The structure can be configured to restrict propagation of the emission from the nanocrystal along the waveguide.

Abstract: The disclosure relates to a method for depositing films on a substrate which may form part of an LED or other types of display. In one embodiment, the disclosure relates to an apparatus for depositing ink on a substrate. The apparatus includes a chamber for receiving ink; a discharge nozzle having an inlet port and an outlet port, the discharge nozzle receiving a quantity of ink from the chamber at the inlet port and dispensing the quantity of ink from the outlet port; and a dispenser for metering the quantity of ink from the chamber to the inlet port of the discharge nozzle; wherein the chamber receives ink in liquid form having a plurality of suspended particles and the quantity of ink is pulsatingly metered from the chamber to the discharge nozzle; and the discharge nozzle evaporates the carrier liquid and deposits the solid particles on the substrate.
