Web13 de abr. de 2015 · In this work, we demonstrate a MoS 2 transistor with a low voltage and high ON/OFF ratio. A record small equivalent oxide thickness of ∼1.1 nm has been obtained by using ultra high- k gate dielectric Pb (Zr 0.52 Ti 0.48 )O 3. The low threshold voltage (<0.5 V) is comparable to that of the liquid/gel gated MoS 2 transistor. WebReplacing the SiO 2 oxide layer with a high- k dielectric layer gives the concept of the electrical thickness, known by the equivalent oxide thickness (EOT) in which the physical thickness (PT) can be increased to improve the device reliability without increasing the effective thickness of the gate dielectric. most unique words in the english https://stealthmanagement.net
