A solid is a semiconductor if it is an insulator at low temperatures (e.g. T < 40 K for silicon) and is a conductor at higher temperature. Its energy band has a forbidden gap where charge carrier cannot occupy. At low temperatures, the probability of a charge carrier having enough energy to be freely roaming in the solid is about nil. That probability increases with temperature. One reminder, an intrinsic semiconductor (~ pure) is charge-neutral (positive charge is exactly balanced with negative charge) at all temperatures. Hence, a "pure" semiconductor is quite useless. However, when we introduce foreign atoms into the material (e.g. arsenic atoms in silicon), the doped semiconductor is very useful indeed. The useful solids created the modern electronics industry -- semiconductors have mostly replaced vacuum tubes as the technology of choice in electronic devices. Nowadays, it is hard to find a radio, TV, cellular phone, GPS, calculator, computer, etc. without an integrated circuit in it.
What else can I help you with?
How do you obtain n type semiconductors?
by adding pentavalent impurity in d pure semiconducters (like intrinsic semiconducters) is called n type semiconducters
What class of elements are semiconducters?
Metalloids
What are semiconducters used for?
They make computers work.
What are 5 propites of aluminum?
sex
What are some important exports of japan?
Automobiles, transportation equipment, semiconducters and electrical and electronic devices.
What is used to produce a laser?
Chemicals,carbon dioxide,agron gas,and semiconducters produce a laser.
Which combination of n-type and p-type semiconducters would be used to amplify a weak electronic signal?
n-p-n
What are semiconducters?
Semiconductors are materials that have electrical conductivity between that of a conductor and an insulator. They are a key component in electronic devices, allowing for control of electrical signals in transistors, diodes, and integrated circuits. Semiconductor devices are used in a wide range of applications from computer chips to solar cells.
Are semiconducters shiny or dull?
Semiconductors are typically dull in appearance. They are made of materials like silicon or germanium, which do not have a reflective surface like metals but rather have a matte finish.
How a transistor constructed?
They contructed using semiconducters and metals. BJT(Bipolar junction Transisters) type transisters made by semi conducters. Generally for FET (Field Effect Transisters) type sometimes they add some metals to get the expected output.
What are physical propites?
Physical properties are characteristics of a substance that can be observed or measured without changing the substance's composition. Examples include color, density, melting point, boiling point, and conductivity. These properties help identify and classify different materials.
Does Fuji make other things besides camera equipment?
Fuji Industries makes lots of things other than camera equipment. The company has been around a long time and has there hands in graphic arts, optics, digital devices, semiconducters and medical equipment, just to name a few.
