Description The term nanoelectronics refers to the use of nanotechnology in electronic components. These components are often only a few nanometers in size. This course is allocated to nanoelectronics.
Overview
Nanoelectronics consist of a diverse set of devices and materials in small size. Physical effects alter materials' properties in nanoscale – inter-atomic interactions and quantum mechanical properties play a significant role in the function of these devices. Quantum effects such as tunneling and atomistic disorder dominate the characteristics of these nanoscale devices.

On the other hand, researches on improvements of electronics such as display, size, and power consumption of the device for practical use is known as nanoelectronics. This includes research on memory chips and physical surface modifications on electronic devices.


Booklet
Description
 It talks about devices which can work where there is no invisible light, such as cameras which work with infrared waves. It talks about how they work and its challenge. Then it talks about the use of QDs. It goes through this subject and gives an example of synthesizing quantum dots, which is Stransky-Krastanov. It explains this method in details.
Mental Challenge
 Why do we use QDs in devices which can work where there is no invisible light?
Quizzes and Activities
 Activity: Compare the three types of transition in a table.
