WebJan 15, 2024 · The main advantages of using NiSi are low temperature processing, low silicon consumption, and low resistivity phase compare to other metal silicides [8,9]. However, obtaining low contact resistance below 10 −6 still faces many challenges. WebA photon having an energy at least equal to the work function can eject electron from the metal, frequency of such a photon whose energy is just equal to the work function is called Threshold Frequency. Work Function ; W = h ν o ; Where , ν o is Threshold Frequency. Electrons are, therefore, emitted only if the frequency of the photon is ...
Web4]. However, the NiSi work function is close to the mid-gap of silicon, which makes it unsuitable for high performance MOSFET applications due to high threshold voltages [5]. Metal inter-diffusion gate and nitrogen implantation into a single metal have been suggested to tune the metal gate work function in MOSFETs [6-7]. Recently, doping of the
