Electrostatic MEMS devices with high reliability

The present invention provides for an electrostatic microelectromechanical (MEMS) device comprising a dielectric layer separating a first conductor and a second conductor. The first conductor is moveable towards the second conductor, when a voltage is applied to the MEMS device. The dielectric layer recovers from dielectric charging failure almost immediately upon removal of the voltage from the MEMS device.

Highly reliable stacked white organic light emitting device

An organic light emitting device (OLED) is provided that includes a cathode and an anode; a blue emitting layer; and at least two hybrid red/green emitting layers. One of the at least two hybrid red/green emitting layers is a cathode side, red/green emitting layer that is disposed between the cathode and the blue emitting layer. The second of the at least two hybrid red/green emitting layers is an anode side, red/green emitting layer that is disposed between the blue emitting layer and the anode. The OLED emits white light.

High reliability, long lifetime, negative ion source

A negative ion source includes a plasma chamber, a microwave source, a negative ion converter, a magnetic filter and a beam formation mechanism. The plasma chamber contains gas to be ionized. The microwave source transmits microwaves to the plasma chamber to ionize the gas into atomic species including hyperthermal neutral atoms. The negative ion converter converts the hyperthermal neutral atoms to negative ions. The magnetic filter reduces a temperature of an electron density provided between the plasma chamber and the negative ion converter. The beam formation mechanism extract the negative ions.
