III.8. THE TUNNEL DIODE 1. Theory The Japanese physicist Leo Esaki invented the tunnel diode in 1958. It consists of a p-n junction with highly doped regions. Because of the thinness of the junction‚ the electrons can pass through the potential barrier of the dam layer at a suitable polarization‚ reaching the energy states on the other sides of the junction. The current-voltage characteristic of the diode is represented in Figure 1. In this sketch i p and U p are the peak‚ and iv and U v are

Overconfident Overconfident behavioural is a well-established bias in which someone’s subjective confidence in their judgments is reliably greater than their objective accuracy‚ especially when confidence is relatively high. Management’s overconfident seen through overestimate the chances of success and underestimate the associated risks of its decision. The management’s overconfidence reflected from following evidences: * Management overestimate the chance of project success as stated in Eurotunnel prospectus

addition to the Burleigh drill‚ the next most impressive implementation of technology in blasting of the Hoosac Tunnel involved nitroglycerin. In 1866‚ Thomas Doane imported a liquid and unstable explosive called trinitroglycerin‚ which is called nitroglycerin in America. His decision to think outside of the box and import the substance changed many aspects of the tunneling process. The Hoosac Tunnel was the first location where the explosive was used in the United States‚ and it became an integral part

The Twin Tunnels‚ proposed by the Governor of California jerry Brown‚ are two tunnels that would run from the delta to Southern California. The project would make two tunnels‚ each about 20-40 feet in wide and around 35 miles long‚ that would be 150 feet beneath the Delta. The Twin Tunnels will be extremely expensive especially to taxpayers and very destructive to the Delta’s ecosystems. Much of California opposes them. The goal of the Twin Tunnels is to divert water from the Sacramento

One of the greatest engineering achievements of ancient times is a water tunnel‚ 1‚036 meters (4‚000 feet) long‚ excavated through a mountain on the Greek island of Samos in the sixth century B.C. It was dug through solid limestone by two separate teams advancing in a straight line from both ends‚ using only picks‚ hammers‚ and chisels. This was a prodigious feat of manual labor. The intellectual feat of determining the direction of tunneling was equally impressive. How did they do this

TTYL Carpal Tunnel Thousands of people get this syndrome every year. People wake up in the middle of the night with agonizing pain in their hands and wrists. Carpal Tunnel is very painful and a hassle to deal with‚ but treatable. More and more people have gotten this syndrome because of the technology we use. When people repeatedly do the same motions over a certain amount of time‚ like texting‚ their hands and wrist start to ache and become inflamed. Constant texting and the use of a keyboard

Maturity isn’t something you can just explain in a definition and expect everyone to fit into that category. Although it’s not age based‚ it is something that everyone is unique in‚ with no one on the same maturity level as the person next to them. Gina Barreca discusses this in her article “Maturity is Getting it Done‚ No Whining.” Another article “Critical Convictions: On Maturity” by Donald Vroon states the same topic through very similar ideas. Vroon says “age is no guarantee of maturity. Many

Emotional Maturity Emotions are the foundation of each relationship in our lives‚ and the power of those emotions cannot be overlooked. Emotions often override our thoughts and profoundly influence our behavior – often without our awareness‚ and whether we like it or not. Most people seek relationship advice to find answers to problems they believe are responsible for their conflicts—without realizing there are more fundamental issues at the root of those problems. They are attempting to heal
