This chapter contains the theories and effective parameters for developing the electronic applications by using nanotechnology techniques. This chapter sheds light on developing characterization of surface plasmon resonance (SPR) sensor, organic light emitting diode (OLED), thin-film transistors (TFTs), compact microstrip patch antenna, semiconductors, resistive memories, memory ram, chemical sensors, biosensors, and super capacitors. Furthermore, this chapter contains the detailed literature of the effects of different types and concentrations of nanoparticles for developing characterization of electronic applications. Finally, this chapter draws attention to the recommendations for investment in electronic applications by using nanotechnology techniques.
