a r t i c l e i n f o Keywords: ab initio double defect method cluster expansion thermal modeling solid solutions The thermodynamic mixing functions of MgSiO 3 –Al 2 O 3 solid solutions in perovskite and ilmenite structures were modeled based on the results of ab initio calculations applied to a set of supercell structures containing 64 and 48 exchangeable… (More)
Graphene-based organic light-emitting diodes (OLEDs) have recently emerged as a key element essential in next-generation displays and lighting, mainly due to their promise for highly flexible light sources. However, their efficiency has been, at best, similar to that of conventional, indium tin oxide-based counterparts. We here propose an ideal electrode… (More)
Recall that we have reduced the 1–2% shrinkage tolerance commonly specified by laboratories to about a quarter by taking into account Ref. 10. However, the fabricated circuit has entirely exhausted the envisaged range. Yet, the insertion loss is still very good. Within the envisaged band, the reflection coefficient remains <À10 db, for 74.5 GHz and above at… (More)
