Plasma-enhanced molecular layer deposition (PEMLD) of boron carbide dielectrics from carboranes for interconnect and patterning applications
(2022)The dimensional scaling of semiconductor devices following Moore’s law has resulted in smaller, faster, and cheaper integrated circuits (IC) chips, going from ~3000 transistors in an IC chip in the early 1970s, to ~100 ... -
MAX-phase Partial Optical Properties
(2022)The optical and electrical properties of MAX-phase materials have been thoroughly studied in the past. We present here a new technique to determine and study the partial contributions to the optical properties. Following ... -
Sampling Schemes For Estimating Software Reliability
(2022)Any software system of non-trivial size cannot be easily and completely tested because the domain of all possible inputs is complex and very large. In this study, we use a technique called partition testing, in which we ... -
