TeraHertz Transistors

Vysakh August 6, 2011 4 Comments
Terahertz transistors are the new generation semiconductor transistors developed by Intel Corporation. The researchers in Intel had developed a new transistor structure that maintains Moore’s law and would lead them into the discovery of these high speed new generation transistors. The terahertz transistor basically has higher speed (in GHz), High power efficiency, and high heat reduction capacity. These transistors have a fast switching rate of more than trillion times per sec. They also have the capability to perform 50...

Hypersonic Sound Technology

Vysakh July 20, 2018 1 Comment
Image Credit Hypersonic Sound (HSS) is one of the most revolutionary digital sound reproduction technologies of this century. It is considered one of the most innovative approaches to sound engineering. This technology was developed by American Technology Corporation. The biggest advantage of this technology is that it does not include any complex electronic circuits having enclosures, crossovers, woofers, and midrange or tweeter elements as compared to a conventional loudspeaker system. This technology also provides ideal characteristics to almost all...

Thin Film Solar Cell

Vysakh June 6, 2011 8 Comments
Thin film solar cells are the new generation solar cells that contain multiple thin film layers of photo voltaic materials. The thin film solar cells (TFSC) are also known as Thin Film Photo Voltaic cell (TFPV). The thicknesses of thin film layers are very less as (few nano meters) compared to traditional P-N junction solar cells. According to the type of photo voltaic material used, the thin film solar cells are classified into four types. They are 1) Amorphous...
