Design and fabrication of field-effect III-V Schottky junction solar cells
… on design and fabrication of single and multi-junction solar cells using III-V materials has been shown and proved. Schottky solar cells based on metal-(insulator)-semiconductor (M-I-S) structure have been designed and fabricated using various wide bandgap semiconductors, such as GaAs and …

Fluidic characterization of electric field sensitivity of Ti-GaAs Schottky junction gated field-effect biosensors
… of fluid gated metalsemiconductor hybrid (MSH) Schottky structures consisting of a Titanium layer on ntype GaAs. Compared to standard field-effect sensors, the MSH Schottky structures show 21 times larger resistance change with electric field at -46.6 V/cm. The fluidic gate voltages are mirrored …

Electrical characterisation of emerging photo anodes suited to water dissociation with an applied bias
… such as indium-tin-oxide, which would create a Schottky junction with the silicon below, or to use very thin oxides such as titanium dioxide, which when a catalyst is deposited on top creates a MOS structure. Of interest to the first option are the electrical properties of the Schottky junction …

Synthesis and characterization of TiO2 nanotube Schottky diodes
… rectifying metal-semiconductor interface, or Schottky junction, throughout an ordered array of semiconducting nanotubes. The atomic layer deposition (ALD) technique offers a precise, conformal growth mechanism and was used to deposit a continuous platinum (Pt) Schottky contact throughout the …

Energy level engineering in colloidal quantum dot solar cells
… may be attained for ZnO / PbS QD heterojunction photovoltaics through the incorporation of a MoO3 interlayer between the PbS QD film and the top-contact anode. The deep-work-function MoO3 layer mitigates a Schottky junction that would otherwise form at the PbS / anode interface, …

Visible and Infrared Light Detection Using 2D Materials
… within the 10 µm - 20 µm band. Specifically, schottky junction thin-film Platinum (Pt)/WSe₂/Gold (Au) were shown to exhibit large improvements in the short circuit current and open circuit voltage due to antireflection coating effects, surface doping, and surface trap passivation. A single …

High Temperature SiC Embedded Chip Module (ECM) with Double-sided Metallization Structure
… surrounding the chip, but chiefly caused by the Schottky junction and the chip passivation layer. Finally, steady-state and transient measurements are conducted in terms of the thermal measurements. The steady-state thermal measurement is used to demonstrate the cooling system reduction. To …

Electrical detection of atmospheric pollutants and detergents on silicon
… (NO2), and silicon surfaces on ambipolar silicon junctionless nanowire transistors (Si-JNTs) (Chapter 2). Experimental work and density functional theory (DFT) modelling demonstrate that NO2 functions as a "pseudo" molecular dopant, influencing key device parameters across p-type and n-type …

Design of Novel Devices and Circuits for Electrostatic Discharge Protection Applications in Advanced Semiconductor Technologies
… distinct from GaAs, the leaky problem of the schottky junction and the lack of choice of passive/active components in GaN technology limit the ESD protection design, which will be discussed in this dissertation. However, a promising ESD protection clamp is finally developed based on …
