Design rule is an important interface between design and manufacturing. It becomes more complex as the process advances to 16-nm and beyond. Current approaches to generate design rules are empirical shrink and lithographic simulation. However, it is time-consuming and costly to revise design rules for performance boost and yield improvement after design rules are frozen. Early performance gains in...
The ultimate end of CMOS scaling was predicted almost immediately after the now ubiquitous technology was invented by Frank Wanlass in 1963 [1]. Indeed, many possible limitations to downscaling were discussed in the 1970s, 80s, and 90s [2]. In 2003, Zhirnov et al. [3] estimated the minimal feature size of a “binary logic switch” to be around 1.5nm, based on the Heisenberg uncertainty and Landauer...
In this work we present a theoretical study of the effect of random alloy fluctuations in a InGaN inclusion embedded in a GaN nanowire (NW) LED on the electronic and optoelectronic properties. The calculations are based on an empirical tight-binding (ETB) model, while strain is calculated with a valence force field (VFF) method. Energy gaps distributions are obtained and an optical spectral broadening...
The results of a study concerning the intrinsic noise in low-doped n-type InP crystals operating under static, periodic or fluctuating electric fields are shown. To simulate the dynamics of electrons in the bulk, we employ a Monte Carlo approach, by taking into account the main details of band structure, scattering processes, as well as heating effects. The noise features are investigated by computing...
