Thin film transistor (TFT) is a field effect transistor designed and made by depositing thin films obtained from a semiconductor’s active layer, alongside the dielectric layer with metallic contacts supported by a suitable substrate such as glass. Two electrodes are directly…

Digital radiography has seen drastic improvement since the adoption of TFTs in general radiography. This technology has also been used in the Active Matrix OLED (ALOMED) screens.
Klauk, (2006, pp41-47) states that organic transistors are transistors that are made using thin films from an organic semiconductor instead of inorganic semiconductors in their channel. Small organic molecules may be evaporated in a vacuum to make the organic transistor. Alternatively, organic transistors are prepared by solution casting and transfer of organic single crystalline layers on a suitable substrate. The principal idea is the use of an organic material as the active semiconductor, to replace the initially used macromolecular organic materials (polymers) to increase efficiency. Electropolymerisation may still be used in case of unavailability of suitable and commonly used organic semiconductors (Brazis, Gamota, Kalyanasundaram & Zhang, 2004, p9).
Optimization of structural design and devise interfaces led to several construction designs formulations but the most widely used are top and bottom contact Organic Thin Film Transistors (OTFTs). The terms top and bottom refer to the position of the two electrodes in relation to the position of the semiconductor.
Top-contact OTFTs have their thin semiconductor film layer deposited first, then followed by the source and drain electrodes contacts onto the gate dielectric. A considerable reduction in contact resistance at the two electrodes; therefore they have little structural disorder at the interface.
Bottom contact OTFTs have their source and drain electrode contacts first deposited first onto the gate dielectric supporter then the organic semiconductor crystal structure deposited directly on top. Molecular layers in the crystal structure are laid in a less ordered manner during the deposition onto the source and drain electrodes.
While top contact OTFTs have reduced contact resistance and

Name: Instructor’s Name: Course: Date of Submission: Organic Food Outline The organic food industry has been booming in the United States. This has resulted in many arguments regarding the fact that whether organic food is superior in nutritive value and has other benefits over the conventional foods.
Organic Food Organic food products are products which are produced without conventional fertilizers, pesticides, biotechnology, irradiation, growth hormones, antibiotics, genetic engineering and artificial ingredients. (Cccindia, n.d.) Since the 1990s the organic product market has experienced rapid growth.
The objective of the report is to gain better understanding about different aspects of organic foods and how it is different from transgenic foods and regular food items in terms of safety and taste. The report is intended to highlight the disadvantages of organic foods and transgenic foods which can increase the concern among its consumers.
The structures in the OTFT and OTFMT as (MIS) where PMMA was fabricated by a spin coating to produce 300nm of thickness and gold nanoparticle was formed between PMMA layers and sandwiched using thermal solution with the gold nanoparticle solution (Fakher & Mabrooka, 2012).
This is because transistors are in place to monitor energy efficiency and speed of processors. The better the transistor platform therefore, the better the overall output of a mobile device, as the device would have a highly advanced operational platform to process data inputs.
Organic farming is a young growing industry. In general terms, it is built around the idea of producing food that green, clean, and healthy. In other words, the production process is designed to use sustainable products, and no part of the process uses any form of artificial chemicals to enhance its products.
be fabricated at low price and low temperature due to the flexible nature of the organic electronic materials, which are the conductive polymers, used in these devices, which is not attainable from their inorganic counterparts such as silicon, copper, etc. Conductive polymers
The difference is that in the former, holes are the majority carriers whereas electrons are the major carriers in the n-type. Also, the p-type tends to have much better mobility. The focus herein is on the p-type. The basic structure of an
Organic foods have a growing market, even though they have higher prices than conventional foods (Winter and Davis 118). The high demand for organic foods can be attributed to the benefits obtained from the food substances. Organic foods are nutritious and healthy because they do not contain harmful chemicals in farming.
