Abstract: A method for producing hyperthermal molecular hydrogen is disclosed and use of same for selectively breaking C—H or Si—H bonds without breaking other bonds are disclosed. A hydrogen plasma is maintained and protons are extracted with an electric field to accelerate them to an appropriate kinetic energy. The protons enter into a drift zone to collide with molecular hydrogen in gas phase. The cascades of collisions produce a high flux of hyperthermal molecular hydrogen with a flux many times larger than the flux of protons extracted from the hydrogen plasma. The nominal flux ratio of hyperthermal molecular hydrogen to proton is controlled by the hydrogen pressure in the drift zone, and by the length of the drift zone. The extraction energy of the protons is shared by these hyperthermal molecules so that average energy of the hyperthermal molecular hydrogen is controlled by extraction energy of the protons and the nominal flux ratio.

Abstract: Method for growing multilayer polymer based hetexjunction devices which uses selective breaking of C—H or Si—H bonds without breaking other bonds leading to fast curing for the production of layered polymer devices having polymer heterojunctions deposited by the common solution-based deposition methods.

Abstract: Method for growing multilayer polymer based heterojunction devices which uses selective breaking of C—H or Si—H bonds without breaking other bonds leading to fast curing for the production of layered polymer devices having polymer heterojunctions deposited by the common solution-based deposition methods. In one embodiment, a hydrogen plasma is maintained and protons are extracted with an electric field to accelerate them to an appropriate kinetic energy. The protons enter into a drift zone to collide with molecular hydrogen in gas phase. The cascades of collisions produce a high flux of hyperthermal molecular hydrogen with a flux many times of the flux of protons extracted from the hydrogen plasma. The nominal flux ratio of hyperthermal molecular hydrogen to proton is easily controllable by the hydrogen pressure in the drift zone, and by the length of the drift zone.

Abstract: Method of controlling the morphology of self-assembled monolayers (SAMS) on substrates having hydrophilic surfaces. The hydrophilic surface is exposed to a fluid having a mixture of molecules which can self-assemble on the hydrophilic surface and hydrophobic molecules for a sufficient length of time so that the molecules which can self-assemble on the hydrophilic surface form a complete self-assembled monolayer. In a particular embodiment octadecylphosphonic acid (OPA) molecules have been self-assembled on oxidized substrates including but not limited to mica, silicon, sapphire, quartz and aluminum by spin-coating a solution containing the octadecylphosphonic acid (OPA) molecules and hydrophobic molecules such as chloroform or trichloroethylene under a controlled relative humidity. Control of the morphology of OPA SAMs is affected by adjusting humidity and the duration of spin-coating. Atomic force microscopy revealed that relative humidity has a profound influence on the morphology of the OPA SAMs formed.

Abstract: A scanning probe based method to selectively remove self-assembled organic molecules from their self-assembled monolayer (SAM) prepared on a conducting/semiconducting substrate having a hydrophilic surface. This technique involves the use of a conductive probe tip scanning a SAM with a thickness of not more than a few nanometers under an electric field applied by the scanning tip with a field strength of about 109 V/m between the tip and the surface of the conducting/semiconducting substrate. The patterned SAM can be used a device mould for the development of a nano-lithography technology or a device element in the fabrication of a nano-device. The present invention accommodates the trend of ever-decreasing size of devices.
