Maximum density rule for bulk terminations of quasicrystals

Bulk electronic structure of quasicrystals.

We use hard x-ray photoemission to resolve a controversial issue regarding the mechanism for the formation of quasicrystalline solids, i.e., the existence of a pseudogap at the Fermi level. Our data from icosahedral fivefold Al-Pd-Mn and Al-Cu-Fe quasicrystals demonstrate the presence of a pseudogap, which is not observed in surface sensitive low energy photoemission because the spectrum is aff...

Maximum Allowable Bulk Defect Density for Generation–Recombination Noise-Free Device Operation

Generation–recombination noise associated with bulk defect levels in silicon is modeled in a partial differential equation-based device simulator to study the maximum allowable defect density that guarantees generation-recombination (g–r) noise-free operation in the presence of hotcarrier effects and space-charge injection.

Swelling Bulk Density and its Application in Arya and Paris Model for Soil Moisture Curve Prediction

The Bulk Carrier Maximum Optimal Ship Size

The main objective of this paper is to investigate the economical limit for the ships’ increase in size. Ship size is one factor out of many that affect the investors in the shipping business. The paper seeks to reassess the validity of well-established theoretical frameworks, which support the concept of depending on the increase in size of ships prompted by economies of scale. The investigati...
