Abstract: In this paper, we have explained the characteristics of semiconductors diodes and its application have influenced the universe beyond anything before they might have thought. While the communications and processing records have been nonetheless essential via the humans, thanks to the semiconductors all vital duties have been conveniently accomplished and infinitely less time has been needed than, for example, during vacuum tubes. The Semiconductor diode that is made from a small piece of semiconductor material, usually silicon, in which half is doped as a p region and half is doped as an n region with a p-n junction and depletion region in between. In order to review the semiconductor diode, we used unbiased, forward-biased and reverse biased methods. In unbiased condition the external voltage does not apply on the p-n Junction, In forward bias the P-region of the diode is connected with the positive terminal of the battery and N-region is connected with the negative region. While in the reverse bias, the P-type region is connected to negative voltage and N-type is connected to the positive terminal The building blocks of the entire electronics and computing sectors are semi-conductive substances. Without included circuits (chips) which consist of semiconductor substances, compact, lightweight, excessive velocity and coffee-energy gadgets might no longer be possible. This essay explores the general records, description and impact of semiconductors on semiconductors. Statistics on the effects of temperature on mosfet band difference, carrier density, mobility, provider diffusion and speed saturation, contemporary density, threshold voltage, leakage cutting-edge and interconnection resistance are given below. We also provide the applications of semiconductor materials in different sectors of modern electronics and communications.

Abstract: To make sure that all significant contractual obligations are documented and managed, it is essential to have a clear understanding of construction contract agreements. However, the text data that makes up the content in these papers frequently necessitates the use of text mining. The topic modelling method of text mining, which is based on the document's topic, is one possible strategy to address these. The objective of this research is to demonstrate whether meaningful knowledge relationships can be extracted from a sample construction specific document using topic models (i.e. LDA). The research used a contract administration manual for topic modelling which is prepared by the Ethiopian Roads Authority (ERA) for use by the Regional Roads Authorities (RRAs). A total of 3217 unique tokens were available for text analysis. Between 5 and 25 topics were specified for LDA training and the one with 5 topics had concise result. To enhance the interpretability of the topics; topic visualization, relevance metric and filtered noun-types approaches were used. The tuning parameters in LDA Gensim with 5 topics gave the highest coherence score of 0.5163. Topic 1 made up the biggest portion of topics constituting 27% of the tokens. In addition, topics were made more interpretable by adjusting their setting. A total of 24300 bigrams and trigrams were also filtered with noun structures to form a unique concept. Construction companies benefit much from knowing what is under construction documents. An automated domain-specific model is required that can precisely extract all the explicit and implicit criteria from the construction contracts since construction-specific contracts differ from those used in other industries. In order to ensure that all pertinent project requirements are recorded, the research aims to demonstrate how knowledge linkages may be derived from construction-specific documents using topic models (i.e. LDA).
