Semiconductor device

Everyone wants so much more power and performance, but without the bulkiness that inevitably comes with it. Since the first commercially sold cell phone in 1983 (Seward, 2013), advancements in technology have been able to reduce the size of cellular devices significantly. The size of the phone from 1983 was over 14 inches long, and it did not even have a screen (Seward 2013). The average size of a cell phone now is approximately 5.5 inches and it is 90%…

Introduction Quantum dots (Q-Dots) is very small semiconductor particles that means it can be either conductors or resist electricity depending on the temperature and purity of the semiconductor. Q-dots range in size from 2-10 nm, so because of their small size, quantum mechanics governs the physics of the particles. The synthesis Q-Dots were first studied in 1982 by Efros and Ekimov, and then many developments have reported the synthesis of semiconductor nanoparticles.1 Q-Dots have unique…

Roadmap for semiconductors is no longer aimed at Moore 's Law, according to an article in the <>, the world 's best-known academic journal. 50 years of the myth of the chip industry has finally been broken. 50 years ago, Gordon Moore predicted the development of the chip industry: When the price is constant, the performance of silicon chips every 18-24 months will be doubled. In fact, all this is unavoidable, since 1990, the semiconductor industry has developed a two-year semiconductor…

Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…

Supplemental information for “Colloidal Type-II CdS/ZnSe NCs : Synthesis, Electronic Structures, and Spectroscopic Properties” S.A. Ivanov, A. Piryatinski, J. Nanda, S. Tretiak, D. Werder, V. I. Klimov Theoretical model. To describe quantum states in a spherically symmetric Type-II core/shell nanocrystals (NC) characterized by the core radius R and the shell width H, we use effective mass approximation. We assume the existence of single energy bands for both electrons and holes. This assumption…

Dipole-dipole array has wide using in resistivity/I.P. surveys because of the low E.M. coupling between the current and potential circuits. The arrangement of the electrodes is shown in Figure( )., Electrodes c1 and c2 are separated by a distance (a), and electrodes p1 and p2 are separated by a distance (b). the distance between the potential electrodes pair c1-c2 is the same as the distance between the potential electrodes pair P1-P2 and the distance between the centers of the respective…

This past term I went on a college visit to Capri. Capri is a college for people to learn hair, makeup, and massages. When we got there, we walked in and there were people at the front desk asking names. once they have your name they gave you a small piece of paper that you had to fill out; so your name could be put in a drawing for a prize. You could walk around to the different stations they had there to look at all the things they had. the first on I went up to was the hair. My mom and me…

electrical wire harmed my hand. It is dangerous and risky to work in this section. Also, if you do any simple mistake you will be in a trouble like if you put a group of wires in a wrong place, the information would be sharing with another servers or devices. This kind of problems maybe it makes the company lose everything, and it happens a lot, it is a common mistake. After that, I was too lazy to get up, and I felt like not doing any thing. I hated everything, and I didn’t want to do anything.…
