Abstract
Heterotransistors and heterostructure lasers are old technologies that are really just recently coming into general use. ... Heterotransistors and heterostructure lasers are important technologies in todays society, so important that the inventors shared the 2000 Nobel Physics Prize (along with another gentleman). Through reading this paper one should grasp a better understanding of heterotransistors and heterostructure lasers. ... 4

Introduction to Heterostructures
During the mid 1900s the first heterotransistors and heterostructure lasers were thought of, created, and implemented into various uses in society. ... Their inventions paved the way to the heterostructure equipment we have and use today.
Definition
What is a heterotansistor / heterostructure laser? ... The heterostructure laser uses much of the same technology needed for the transistor. ... Alferov is credited for creating the first heterostructure laser that was able to work at room temperature. ...
Development of the Heterotansistors and Heterostructure Lasers
In 1954 Herbert Kroemer wrote a paper on heterostructures, but gave up because nothing was known at the time about the semiconductors alloys. In 1957, Herbert Kroemer published his first work pertaining to the proposal for a heterostructure transistor. ... In the case of heterotransistors and heterostructure lasers, it took years. ... Satellite dishes and their links, solar panels, optical broadband links, laser printers, bar code readers, laser pointers, and much more all use heterostructure technology. Cellular phones use heterostructure technology in the fast transistors at the base stations. The little blue laser that reads CDs in a cd player is actually a laser diode which contains a semiconductor heterostructure. Heterostructure Lasers used in Cd players dominate in number of units produced while the heterostructure lasers used for communication (cell phones) bring in the most money. ... and Russia were able to produce lasers that worked continuously at room temperature. Recent research has really dramatically increased early heterotransistors speed and perfected heterostructure lasers due to a better understanding and use of materials used.
