OLED Display with Single Grain Si TFT. (SG-TFT)

OLED is a current based device, which emitted amount of light depends on the current supplied to the device so steady current flow is needed. In Active Matrix Organic Light Emitting Diode (AMOLED) Display. TFTs are used as driving transistors for OLED. Because of the non uniformity of the TFTs, variation in threshold voltage and mobility has a...

Carbon nanotubes as vertical interconnects in 3D integrated circuits

In integrated circuits the delay caused by interconnects, their power consumption, production and reliability are challenges to be solved. Using the third dimension for additional layers of transistor has been proposed as a solution to this problem by reducing the length of the interconnects. A problem in 3D integration is the creation of...

SRAM in Three Dimensional Integrated Circuits

In most of the electronics and communication devices such as mobile, video phone and handheld video games low power and high density SRAM (Static Random Access Memory) is a favor. On the other hand, integration of many functions such as digital, memory, RF and analog circuits is necessary in near future. Scaling is one of the solutions to...

Optimisation of a protocrystalline hydrogenated amorphous silicon top solar cell for highest stabilised efficiency

In recent decades, the public awareness of the need for renewable energy sources has increased greatly. Considering the current climate changes, it is clear that today’s energy systems have to be radically transformed onto a more sustainable basis to avoid the otherwise very likely adverse effects of global warming on tomorrow’s society and...
