Professor Munseok JEONG and researcher Ngoc Thanh Duong (in the doctor’s course) has developed a device technology through a joint research with Prof. Sungjoo LIM. The newly developed device is able to output different notation system (binary, ternary and quinary at maximum) depending on the existence of light. It has been posted on the world renowned journal ACS Nano(IF=13.709)’s April 23rd issue.
A normal integrated circuit operates by storing either 1 or 0 as a “bit”. This is because the output of a device is recognized by two types: on and off. If an output larger than ternary notation can be realized in a device, it can extensively improve the performance of integrated circuit.
The minimal unit of computer data processing “byte” uses 8 “bit” as the standard unit. Setting 1 byte as a standard, 6561 outputs can be produced by using ternary notation. This is 25 times greater than the binary notation, which produces 256 outputs. Also, if it is possible to realize a quinary notation, the performance will improve 1000 times with just a single byte.
