Question

observation on telegraph​

Answer 1

Answer:

Current fluctuations with discrete levels, which are called random telegraph signals (RTSs), have been studied in small size metal‐oxide‐semiconductor field‐effect transistors (MOSFETs) from both viewpoints of relative current change and of correlated switchings. A large relative current change of as much as 30% has been observed, even at room temperature. It behaves similarly as normal small RTSs in terms of statistics and temperature dependence. RTSs have been found also in 20‐μm channel width MOSFETs. These results require another mechanism to explain RTSs in addition to simple Coulomb scattering or number fluctuation. It is emphasized that an interaction between defects at the Si/SiO2 interface is necessary to understand the correlated RTSs.
