As SciTechDaily points out, a transistor is a small component that allows current to flow or block current based on whether or not a voltage is applied to the control electrode. This architecture allows you to create simple logic circuits, and when you compress billions of them into one package, you get something like a modern processor (in the simplest terms of course). p>
by default. Unipolar transistors contain negatively charged electrons. Single atoms have a positive charge by removing one electron. The researchers' prototype works a little differently. p>
< p> In addition to the normal control gate (red), there is also a program gate (blue).
"We have two very thin electrodes," the wire is made of, said Dr. Misyar Al-Sistani, one of the researchers who worked on the project. p>
The germanium section is a gate electrode similar to that of conventional transistors. The catch is that our transistor has another control electrode located on the interface between the germanium and the metal. Al-Sistani added: "This can dynamically program the operation of the transistor.
The researcher also explained that germanium was chosen due to its special properties.
"When a voltage is applied to you, the flux is flowing. The flow increases at first as you would expect. However, after a certain threshold, the current decreases again - this is called negative differential resistance. With the help of a control electrode, we can adjust the voltage at which this threshold is. p>
This design allows, according to Al-Sistani, new degrees of freedom that can slowly determine the exact characteristics of the desired transistor at any given time. p>
Walter Weber, Masar al-Sistani and Raphael Buckle (from left to right) the desired is now possible. With only 24 transistors thanks to the new design. At this rate, it doesn't take much imagination to imagine how this development could drastically affect efficiency and operating frequency.
“We do not want to replace an established silicon-based transistor. Technology with a new transistor will be very conceited,” Sistani said. The new technology will likely be included as an add-on for future computer chips.
More information on the new transistor can be found in a recent article on the American Chemical Society website..
