We present a parameter extraction technique for higher-order transport models for a 2D electron gas in ultra thin body SOI MOSFETs. To describe 2D carrier transport we have developed a self consistent Schrödinger-Poisson Subband Monte Carlo simulator. The method takes into account quantization effects and a non equilibrium distribution function of the carrier gas, which allows an accurate descr...
Natural gas is a potent greenhouse but remains an attractive energy resource for good number of reasons. Because complementing the use natural with carbon dioxide capture and storage yields several drawbacks, producing synthetic instead could be interesting alternative. Methanation established well-known process, atmospheric as input it deliver climate-neutral carrier, which we refer to renewab...
An integrated system of a microreformer and a carrier allowing for syngas generation from liquefied petroleum gas (LPG) for micro-SOFC application is discussed. The microreformer with an overall size of 12.7 mm × 12.7 mm × 1.9 mm is fabricated with micro-electro-mechanical system (MEMS) technologies. As a catalyst, a special foam-like material made from ceria-zirconia nanoparticles doped with r...
The (3 1 1)A and (5 1 1)A planes of GaAs were used for the growth of high-quality two-dimensional hole gas (2DHG) and electron gas (2DEG) structures, respectively. A back-gated, inverted interface, AlGaAs/GaAs structure in which a 2DHG or a 2DEG was embedded was studied. This particular structure enabled the two-dimensional carrier concentration to be varied over two orders of magnitude in a si...
the biggest challenges faced in big cities are greenhouse gas emission and growing energy needs. efficient utilization of existing infrastructures has a prominent role in response to the challenges. energy hub approach embraces performance of different energy networks. energy hub is defined as a super node in electrical system receiving distinctive energy carriers such as gas and electricity in...
