Identification of ultradilute dopants in ceramics [PDF]

Nature Materials, 2003
The properties of ceramic materials are strongly influenced by the presence of ultradilute impurities (dopants). Near-edge X-ray absorption fine structure (NEXAFS) measurements using third-generation synchotron sources can be used to identify ultradilute dopants, provided that a good theoretical tool is available to interpret the spectra.

Reversing stealthy dopant-level circuits [PDF]

Journal of Cryptographic Engineering, 2014
A successful detection of the stealthy dopant-level circuit trojan, proposed by Becker et al. at CHES 2013 [1], is reported. Contrary to an assumption made by Becker et al., dopant types in active region are visible with either scanning electron microscopy SEM or focused ion beam FIB imaging.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
