Advanced Multilayer Amorphous Silicon Thin-Film Transistor Structure: Film Thickness Effect on Its Electrical Performance and Contact Resistance

We report the intrinsic and extrinsic electrical characteristics of advanced multilayer amorphous silicon (a-Si:H) thin-film transistor (TFT) with dual amorphous silicon nitride (a-SiNX:H) and a-Si:H layers. The thickness effect of the high electronic quality a-Si:H film on the transistor’s electrical property was investigated; with increasing film thickness, both field-effect mobility and subt...

Effect of Thickness on the Structural Properties of Tellurium Film Prepared by Thermal Evaporation

In this research, tellurium (Te) film with thicknesses of 100-250 nm were deposited on ceramic substrates by thermal evaporation at 373 K. The thickness of the film was determined by Rutherford backscattering spectroscopy. The influence of the thickness on the structural, morphological and molecular bonds was characterized using XRD, scanning electron microscope, and Raman spectroscopy. The XRD...

Emission reabsorption laser induced fluorescence (ERLIF) film thickness measurement

This paper presents a unique optical technique that utilizes the reabsorption and emission of two fluorescent dyes to accurately measure film thickness while minimizing errors caused by variations in illumination intensity and surface reflectivity. Combinations of dyes are selected that exhibit a high degree of emission reabsorption and each dye concentration is adjusted to create an optically ...
