When talking about material that embraces the art of conductivity, it is the semiconductor. In fact, the electric conductivity in these materials is due to the fact that flowing electrons which are the magnitude between that of an insulator or the conductor. All of the devices that are made from the semiconductor material are the foundation of modern electronic which includes computers, radio, home appliances and all electronic devices. The Semiconductors, which are found in the transistors and microprocessor chips has made a huge impact in our world today.
Know the Basics
Silicon is the material used as a semiconductor in the microprocessor transistor and chips. Have you heard about ‘Silicon valley’ or ‘Silicon economy’? These two places were both derived from the world silicon, which are the heart of any electronic devices. Silicon is a very common element in sand and quartz. Scientifically speaking, if you look at silicon in the scientific way, for example, in the periodic chart you will find silicon has aluminum on one side, on the top, Carbon and below it is the germanium. These 3 material Germanium, Silicon and Carbon have a unique property in their structure of electrons where each has 4 electrons in the outer orbit, and having electrical conductivity, which is greater compared to that of insulators but are less than good conductors, and are used especially as a base material for electronic devices and computer chips.
When it comes to a very good conductor of electricity, metals are the very reason on why they usually have ‘free electrons’ that can easily move between electricity and atoms involve the flow of electrons. Silicon crystals, on the other hand, look metallic, but take note that it is not metal. The silicon’s outer electrons are involved in perfect covalent bonds, so they don’t move around. Basically, the pure silicon is an insulator and little electricity that flows through it. This structure of electrons can be changed is called a doping process. The process of doping means adding impurities in a controlled manner to Silicon. The amount of dopant or impurity added to an intrinsic Semiconductor determines the conductivity level of the Semiconductors. Because of these properties, the Semiconductors is helpful in making electronic devices so that their conductivity can be modified easily as required through doping.
Opportunity for Investors
According to the current statistics, the semiconductor industry has grown and is expected to grow to a greater extent in future. However, this figure is just an average estimation, if the sales growth of each company is analyzed, there will be a more commendable growth being observed. All in all, the performance of the semiconductor industry has remained exceptionally well. The demand and supply for the stocks of this industry has proven or shown an upward trend, which is verified by the sector’s industrial growth.
When it comes to the electronic devices, semiconductors are the groundwork because they are the heart of the computer and the core of every electronic devices. So, don’t overlook its importance!
