      Investigation into the charge distribution and barrier profile tailoring in AlGaN/GaN double heterostructures by self-consistent Poisson-Schrödinger calculations and capacitance-voltage profiling 

      Zervos, Matthew; Kostopoulos, A.; Constantinidis, G.; Kayambaki, M.; Georgakilas, A. (2002)
      The two-dimensional electron gas (2DEG) distribution and conduction-band profile tailoring of the Al xGa 1-xN/GaN/Al yGa 1-yN/GaN double heterostructure (DH) has been studied in detail by self-consistent Poisson-Schrödinger ...

      Tribological behavior of CrN and Al-Cr-N coatings 

      Demas, N. G.; Polycarpou, A. A.; Polychronopoulou, K.; Rebholz, Claus (Affiliation: Department of Mechanical Science and Engineering, University of Illinois at Urbana-Champaign, Urbana, IL 61801, United StatesAffiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, 1678, Nicosia, CyprusCorrespondence Address: Demas, N. G.Department of Mechanical Science and Engineering, University of Illinois at Urbana-Champaign, Urbana, IL 61801, United States, 2009)
      The tribological behavior of CrN and Al-Cr-N coatings prepared by twin electron-beam evaporation at 450°C was investigated. The composition, structure, mechanical and tribological properties of the coatings were determined ...
