“…First, its higher mobility and saturation drift velocity mean that electrons can move faster in GaAs than in Si, and therefore devices can operate at higher frequencies. GaAs digital circuits run two to five times faster than Si circuits and have lower power dissipation [1,2,3,4]. In analog applications, Si transistors are hard pressed to operate above 10 GHz.…”

In this article we present a complete overview of our investigation on deep trap states in molecular beam epitaxy (MBE)-grown Si-implanted, low temperature (LT)-GaAs and high-temperature (HT)-GaAs by field effect deep level transient spectroscopy (FEDLTS). The LT-GaAs and HT-GaAs samples were grown at 300 o C and 750 o C, respectively. FEDLTS studies were conducted on Schottky diodes fabricated on these samples using Au contacts in the temperature range 100−350 K. We have included the lambda-effect and lambda-delta effect in the determination of deep trap concentrations and capture cross sections. Our study indicates that the deep traps identified in LT-GaAs and HT-GaAs are all bulk deep traps (BDT). No near-surface-deep traps (NDT) were detected in either of these materials. Furthermore, the effective deep trap concentration, in both LT-GaAs and HT-GaAs, increased with temperature showing a two-step linear rise and ending with a tendency to saturate around 350 K. The ionization energy of the carriers indicated a linear relationship with temperature in the above temperature range from 0.05 eV to 0.30 eV for LT-GaAs and from 0.02 eV to 0.12 eV for HT-GaAs.

“…The inspection of pulp quality holds significant importance in guaranteeing that the pulp utilized in the paper production process conforms to the prescribed standards. Through the monitoring of pulp quality, paper manufacturers can ensure the production of high-quality paper products that meet the expectations of their customers (Keyes, 1977).…”

“…Chemical additives are frequently incorporated into the paper manufacturing procedure to enhance the caliber of the resultant paper. The process of chemical dosing inspection entails the careful observation and evaluation of the quantity and nature of chemicals introduced into the production process, with the aim of verifying that they are administered in appropriate proportions and are appropriate for the intended application of the paper commodity (Erickson & Hedrick, 1999;Keyes, 1977;MacGregor & Kourti, 1995;Matos et al, 2008).…”

The purpose of this study is to provide an overview of quality control in the paper industry.Wood preparation, pulping, bleaching, and papermaking are all steps in the papermaking process, and eachone presents its own set of quality control challenges. The study looks at the various methods that are usedin the industry to monitor and control the quality of finished paper products. It includes laboratory testing,statistical process control, and online monitoring systems, as well as traditional and modern quality controltechniques. The study also emphasizes the significance of quality control in the paper industry, which canhave a significant impact on product performance, customer satisfaction, and profitability. Finally, the studyconcludes with a discussion of benefits in the paper industry's quality control.
