Outlook and Emerging Semiconducting Materials for Ambipolar Transistors

Ambipolar or bipolar transistors are transistors in which both holes and electrons are mobile inside the conducting channel. This device allows switching among several states: the hole-dominated on-state, the off-state, and the electron-dominated on-state. In the past year, it has attracted great interest in exotic semiconductors, such as organic semiconductors, nanostructured materials, and carbon nanotubes. … Continue reading

Low Driving Voltage and High Mobility Ambipolar Field-Effect Transistors with PbS Colloidal Nanocrystals

PbS colloidal nanocrystals (NCs) are promising materials for optoelectronic devices, due to their size-tunable properties. However, there is still minimal understanding of their charge transport mechanism. Through a combination of ligand selections, ambipolar transistor structure optimization, and electrochemical gating usage, high carrier mobility is achieved. The outstanding device characteristics open possibility to investigate the intrinsic … Continue reading

SCIENTIFIC METHOD IS THE MOST IMPORTANT THING IN SCIENCE

here is my perspective about science (taken from my answer for graduate entrance examination) Basically, science is a systematic study of anything which could be examined, tested, measured, analyzed and verified to find the truth about the object of study itself. In general, science could be distinguished into two parts, hard sciences and soft sciences. … Continue reading
