Atomic layer deposition (ALD) has emerged as a promising technology for the development of next generation low-power semiconductor electronics. The wafer-scaled growth two-dimensional (2D) crystalline nanostructures is fundamental step toward advanced nanofabrication technologies. Ga2O3 an ultra-wide bandgap metal oxide application in electronic devices. polymorphous with its unique characteris...

Flux-pinning mechanism of MgB2 doped with 10 wt % silicone-oil sintered at low and high temperatures has been investigated by magnetic measurements. The field dependence of the critical current density, jc(B), was analysed within the collective pinning model. A crossover field, Bsb, from the single vortex to the small vortex bundle-pinning regime was observed. For both types of sintered samples...

We propose a semiconductor-superconductor hybrid device for realizing topological superconductivity and Majorana zero modes consisting of planar Josephson junction structure with periodically modulated width. By performing numerical analysis the effective model describing low-energy physics structure, we demonstrate that modulation width results in substantial enhancement gap and, consequently,...

We present a silicon avalanche photodetector (APD) fabricated with standard complementary metal-oxide-semiconductor (CMOS) technology without any process modification or special substrates. The CMOS-APD is based on N+/P-well junction, and its current-voltage characteristics, responsivity, avalanche gain, and photodetection frequency response are measured. Gain-bandwidth product over 1 THz is ac...

There are two types of field-effect transistors, the Junction Field-Effect Transistor (JFET) and the “Metal-Oxide Semiconductor” Field-Effect Transistor (MOSFET), or Insulated-Gate Field-Effect Transistor (IGFET). The principles on which these devices operate (current controlled by an electric field) are very similar — the primary difference being in the methods by which the control element is ...

The principles and applications of semiconductor electrodes in photoelectrochemical cells (liquid junction photovoltaic, photoelectrosynthetic, and photocatalytic) are described. The extension of the principles of these cells to the design of simple particle systems for carrying out light-driven chemical reactions is discussed. [The SCI indicates that this paper has been cited in more than 245 ...

Chemical costs can be a significant part of semiconductor manufacturing materials cost. True chemical cost consists of raw chemical price, handling expenses and disposal of used chemicals. Some of this usage can be cut back by recycling the chemicals for re-use. This paper describes the work done to establish the use of recycled chemical for etch processing during Gallium Arsenide Hetero-juncti...
