Performance Limit Projection of Germanane Field-Effect Transistors
(Institute of Electrical and Electronics Engineers, 2017-03-13)Here we explore the performance limit of monolayer germanane (GeH) field-effect transistors (FETs). We first plotted an electronic band structure of GeH using density functional theory (DFT) and then tight-binding parameters ... -
Quotient Complexity of Bifix-, Factor-, and Subword-free Regular Language
(Institute of Informatics: University of Szeged, 2014)A language $L$ is prefix-free if whenever words $u$ and $v$ are in $L$ and $u$ is a prefix of $v$, then $u=v$. Suffix-, factor-, and subword-free languages are defined similarly, where by ``subword" we mean ``subsequence", ... -
