Super CMOS devices on a microelectronics system
A low cost IC solution is disclosed to provide Super CMOS microelectronics macros. Hereinafter, the Super CMOS or Schottky CMOS all refer to SCMOS. The SCMOS device solutions with a niche circuit element, the complementary low threshold Schottky barrier diode pairs (SBD) made by selected metal barrier contacts (Co/Ti) to P— and N—Si beds of the CMOS transistors. A DTL like new circuit topology and designed wide contents of broad product libraries, which used the integrated SBD and transistors (BJT, CMOS, and Flash versions) as basic components. The macros include diodes that are selectively attached to the diffusion bed of the transistors, configuring them to form generic logic gates, memory cores, and analog functional blocks from simple to the complicated, from discrete components to all grades of VLSI chips. Solar photon voltaic electricity conversion and bio-lab-on-a-chip are two newly extended fields of the SCMOS IC applications.

HIGH EFFICIENCY PHOTOVOLTAIC CELLS AND MANUFACTURING THEREOF
This invention relates to a novel structure of photovoltaic devices (e.g. photovoltaic cells also called as solar cells) are provided. The cells are based on the micro or nano scaled structures which could not only increase the surface area but also have the capability of reducing the reflection and increasing the absorption of incident light. More specifically, the structures are based on 3D structure which are made of electric materials covering semiconductors, insulators, dielectric, polymer, and metallic type materials. By using such structures reflection loss of the light from the cell is significantly reduced, increasing the absorption, which results in increasing the conversion efficiency of the solar cell, and reducing the usage of material while increasing the flexibility of the solar cell. The structures can be also used in other optical devices wherein the reflection loss and absorption are required to enhance significantly improve the device performances.

Metallo-graphene nanocomposites and methods for using metallo-graphene nanocomposites for electromagnetic energy conversion
Nanocomposites in accordance with many embodiments of the invention can be capable of converting electromagnetic radiation to an electric signal, such as signals in the form of current or voltage. In some embodiments, metallic nanostructures are integrated with graphene material to form a metallo-graphene nanocomposite. Graphene is a material that has been explored for broadband and ultrafast photodetection applications because of its distinct optical and electronic characteristics. However, the low optical absorption and the short carrier lifetime of graphene can limit its use in many applications. Nanocomposites in accordance with various embodiments of the invention integrates metallic nanostructures, such as (but not limited to) plasmonic nanoantennas and metallic nanoparticles, with a graphene-based material to form metallo-graphene nanostructures that can offer high responsivity, ultrafast temporal responses, and broadband operation in a variety of optoelectronic applications.
