A study of deep levels of AlGaAs/GaAs heterojunction bipolar transistors

Creator:: Huang, Chun-ta
Abstract:: A study of deep levels of the emitter region of a heterojunction bipolar transistor is investigated using deep level transient spectroscopy (DLTS), deep level admittance spectroscopy (DLAS), thermally stimulated capacitance (TSCAP), and capacitance-voltage (C-V) profiling. The DX center, with an activation energy of 0.45 eV, is the only deep level...

Alternating-current thin-film electroluminescent device physics and modeling

Creator:: Douglas, Allan A.
Abstract:: Alternating-current thin-film electroluminescent (ACTFEL) devices are used in the formation of pixels in flat panel displays. ACTFEL flat panel displays have many advantages over other flat panel technologies. Specifically, ACTFEL panels are emissive displays, they have high brightness, wide viewing angles, and rugged construction. Although much is already known about...

Amorphous metal thin films as a platform for solution processing

Creator:: Landau, Nicholas P.
Abstract:: The research presented herein represents an effort to combine the ultra-smooth surface of an amorphous metal thin ﬁlm (AMTF) with a solution-processed dielectric synthesized via prompt inorganic condensation (PIC). Analysis of dielectric ﬁlm quality is carried out via electrical measurements of metal-insulator-metal (MIM) diodes. Anneals at 500 and 700 °C...

An n-sheet, state-space ACTFEL device model

Creator:: Hitt, John C.
Abstract:: The objective of the research presented in this thesis is to develop, implement, and demonstrate the utility of an n-sheet, state-space alternating-current thin-film electroluminescent (ACTFEL) device model. In this model, the phosphor layer is discretized into n + 1 layers, with band-to-band impact ionization, space charge creation/ annihilation, and luminescent...

Assessment of High Mobility Oxide Thin-Film Transistors

Creator:: Stewart, Kevin A.
Abstract:: The trend towards higher resolution, faster refresh rate active-matrix liquid-crystal displays (AMLCDs) as well as the emergence of active-matrix organic light-emitting diode (AMOLED) displays is driving the demand for amorphous oxide semiconductor thin-film transistors (AOS TFTs) with higher mobility. A physics-based model for carrier transport in an amorphous semiconductor is...

Atomic solid state energy scale applied to novel thin-film solar absorbers

Creator:: Pelatt, Brian D.
Abstract:: The atomic solid state energy (SSE) scale is introduced as a tool for inorganic materials design. The SSE scale is obtained by assessing an average electron affinity (EA) (for a cation) or an average ionization potential (IP) (for an anion) for each atom using data from compounds having that specific...

Development of Amorphous Metal Thin Films for Thermal Inkjet Printing and Microelectronics

Creator:: McGlone, John M.
Abstract:: Due to a lack of grain boundaries, an amorphous metal thin film (AMTF) possesses advantageous mechanical properties and enhanced chemical stability that is potentially useful for thermal inkjet (TIJ) printing applications. The use of an AMTF as a TIJ resistor or cavitation plate could lead to a thinner TIJ cavitation...

Development of high efficiency solar absorbers

Creator:: Ravichandran, Ram
Abstract:: Current cadmium telluride and copper indium gallium diselenide thin-film solar cells (TFSCs) utilize thick absorbers (2 - 4 μm). For efficient carrier extraction in these TFSCs, the absorber layer requires high carrier mobilities and a long minority carrier lifetime, which necessitates the use of a high purity, defect-free thin film....
