摘要:
A Silicon photodetector contains an insulating substrate having a top surface and a bottom surface. A Silicon layer is located on the top surface of the insulating substrate, where the Silicon layer contains a center region, the center region being larger in thickness than the rest of the Silicon layer. A top Silicon dioxide layer is located on a top surface of the center region. A left wing of the center region and a right wing of the center region are doped. The Silicon photodetector also has an active region located within the center region, where the active region contains a tailored crystal defect-impurity combination and Oxygen atoms.

An ionic liquid-channel charge-coupled device that separates ions in a liquid sample according to ion mobility characteristics includes a channel having an inner wall that has a matrix liquid disposed within. An insulating material surrounds the channel, and an introduction element introduces a liquid sample into the channel. The sample is preferably a liquid solution that has at least one ionic specie present in the solution. The device further includes a gating element that establishes at least one charge packet in the channel in response to an externally applied input signal, and a transport element that induces the charge packet to migrate through the channel. The gate element can be a plurality of spaced-apart, electrically conductive, gate structures that are alternately disposable between a high voltage state and a low voltage state. The transport element further includes an application element that applies a variable voltage to the gating element. This application of voltage induces the charge packets to form under the gate structures and, when the voltage applied to an adjacent gate has a higher potential, induces the packet to migrate through the channel in that direction.

The surface-emission cathodes of the invention are constructed so that the cathode body has a free surface over which electrons are efficiently accelerated after injection from a conductive contact. The junction between the free surface and the contact has the property that the height of the barrier to tunneling from the contact to floating surface states associated with the free surface of the cathode body is lower than both the barrier to emission from the contact to vacuum and the barrier to injection from the contact into the conduction band of the cathode body material. Thus under an applied potential, electrons are injected from the contact into floating surface states associated with the free surface. After acceleration, electrons leave the free surface, either emitted to vacuum or injected into another medium.

A flat-panel display contains an emissive cathode structure and a generally flat encapsulating body that surrounds the cathode structure to form a sealed enclosure. The cathode structure contains electronegative atoms (22), which consist of oxygen and/or fluorine, chemically bonded to a carbon-containing cathode (10). Atoms (24R) of electropositive metal are chemically bonded to the electronegative atoms.

摘要:
A cathode structure contains electronegative atoms (22), which consist of oxygen and/or fluorine, chemically bonded to a carbon-containing cathode (10). Atoms (24R) of electropositive metal are chemically bonded to the electronegative atoms. The combination of the electropositive metal atoms and the electronegative atoms enhances the electron emissivity by reducing the work function.

摘要:
A substrate, such as a film of thermally grown silicon dioxide on a silicon wafer is coated with a thin film of polycrystalline or amorphous silicon in the thickness range 0.05-10.mu. deposited by chemical vapor deposition. An encapsulation layer that is a composite of 2 .mu.m thickness SiO.sub.2, 30 nm of Si.sub.3 N.sub.4 is deposited on the thin film. A pattern of stripes is created on this encapsulation layer made of materials, such as titanium, silicon, silicon dioxide and photoresist. A long and narrow molten zone is created in the film with its long axis oriented perpendicular to the lines and is moved with a movable strip-heater over in a direction parallel to the lines in the recrystallization process to establish dislocation and crystalline defects in the film entrained to follow the pattern of the stripes at locations related to the stripes.
