A semiconductor is a material that has an electrical conductivity between that of a conductor and an insulator, that is, generally in the range 10 3 Siemens/cm to 10 -8 S/cm. Devices made from semiconductor materials are the foundation of modern electronics, including radio, computers, telephones, and many other devices. Semiconductor devices include the various types of transistor, solar cells, many kinds of diodes including the light-emitting diode, the silicon controlled rectifier, and digital and analog integrated circuits. Solar photovoltaic panels are large semiconductor devices that directly convert light energy into electrical energy. An external electrical field may change a semiconductor's resistivity. In a metallic conductor, current is carried by the flow of electrons. In semiconductors, current can be carried either by the flow of electrons or by the flow of positively-charged " holes" in the electron structure of the material. Common semiconducting materials are crystalline solids but amorphous and liquid semiconductors are known, such as mixtures of arsenic, selenium and tellurium in a variety of proportions. They share with better known semiconductors intermediate conductivity and a rapid variation of conductivity with temperature but lack the rigid crystalline structure of conventional semiconductors such as silicon and so are relatively insensitive to impurities and radiation damage. There are three popular ways to classify the electronic structure of a crystal. In a single H-atom an electron resides in well known orbits. Note that the orbits are called s,p,d in order of increasing circular current.

1. "Unlimited" web hosting plan - smart marketing technique?
November 16, 2009
The two basic elements of any web hosting plan comprise of: 1) available hard disk space to accommodate the website 2) allowed traffic. Definitions: hard disk space is the space that is allocated for your website by a hosting company; traffic is the amount of data sent and received by visitors to/from a web site. Like in the physical world, any resources, including web resources, have physical restrictions and cost money. It is impossible to have unlimited RAM and CPU as there is no such invention as an unlimited semiconductor (yet!). Why, then, some of the... (read more)

3. Semiconductor Technology - Assumptions Behind Numerous Kinds
November 04, 2009
Semiconductors will not function unless they possess electrical conductivity. The function takes place in the conductor's linkage with the insulator. This is perhaps the most fundamental among a list of principles behind semiconductor technology. But since this is very basic, there are yet other assumptions to take note of. In this regard, it pays to take a peek at the semiconductor kinds that are crucial in some businesses.Basically, semiconductors have very crucial roles in the fields of modern electronics since they are almost always present in computer, mobile phone and radio cre...

17. Research Report on the LED industry of China and the World from 2009 to 2010
August 12, 2009
www.shcri.com- In the 1950s, RCA first found the infrared radiation of gallium arsenide in other semiconductor alloys. LED is a luminescence component made of semiconductor materials. The component has two electrode terminals. Voltage is applied between the terminals and electricity is switched on. And after the combination of electricity and hole, the remaining power is released in form of light. Different materials have different wavelengths and thus send out lights of various colors. This is the basic lighting theory of LED. LED can only be applied in diodes that can send out visible ligh... (read more)

19. Automotive Human Machine Interfaces (HMI) Redefined
August 06, 2009
Human Machine Interfaces, or HMIs, traditionally consist of multiple systems which allow drivers to interact with their vehicle. In today's automotive designs, the HMI also displays any feedback from the vehicle to the driver. This interaction begins the instant one unlocks the car door, continues while driving, and ends the moment the driver gets out and locks the car. It involves the optimal balance of the driver's sensory inputs to make the driving experience both safe and enjoyable. Some of the more commonly recognized HMI system modules for enhancing the driver's experience are keyless en... (read more)

21. Is Your Company Dental Plan Cost A Small Fortune?
August 03, 2009
When I was working in the Semiconductor Industry, as an engineer, I was paying big dollars for my health care. I finally decided to quit my health plan, since I had not used it for 10 years. I was paying around $250 per month and this included a dental plan. This only included me and one other family member. The problem with this health plan was every year at renewal time the company would change to a different provider and the cost would go up and the services would go down. I recently found a membership that made sense to me related to dental insurance. Even though I am now on Medica... (read more)

22. Designing USB Applications with PSoC
July 31, 2009
Design engineers have long been familiar with USB, first introduced in 1995 to replace the aging RS232 interface. It represents a simple, elegant means of communicating with as many as 126 connected devices using a well-defined protocol. However, adding USB to an existing product is not necessarily simple or elegant, and adding it to new projects adds a degree of complexity that may now be largely avoidable. Cypress Semiconductor’s CY8C24794-24LFXI is a member of its popular Programmable System-on-Chip (PSoC) family of mixed-signal arrays. The 24794 includes a full-speed (12 Mbps) USB 2.0 S...

23. Multi-Touch All-Point Touchscreens: The Future of User Interface Design
July 30, 2009
One of the most demanding challenges designers of electronics – especially consumer electronics – face involves user interface design. Interface design requires careful mapping of complex user actions to create an intuitive, usable, and productive experience. Users, with all of their senses – sight, hearing, taste, smell, and touch – sit on one side of this paradigm. On the other side is the device or system that is affected by the output of the user’s five senses. The holy grail for both users and developers is a user interface that most effectively and intuitively leverages the most relevan... (read more)

25. A Look at Modern CPU Fabrication
July 20, 2009
In the heady days of the first computers, vacuum tubes were the driving force behind calculations by virtue of their switching function. This was all overturned with the coming of the transistor, an invention which was officially pioneered in AT & T's Bell Labs in 1947. The transistor was a revolution because of the manufacture process and the base material, silicon, which is globally abundant and therefore cheaper to manufacture.
Silicon is a semiconductor, capable of either allowing current to pass through it or halting its progress. The properties of a solid-state silicon transistor a... (read more)
