Structure of chromium oxide ultrathin films on Ag(111)

Self-organized chromium oxide monolayers on Fe(001)

“…31,37 Among the transition metal ultrathin oxide films, Cr oxide is one of the less investigated (see, for instance, Refs. [38][39][40][41][42]. Chromium oxide forms stable phases in the bulk with different structures, stoichiometry, and properties.…”

Ordered Oxide Surfaces on Metals: Chromium Oxide

“…Previous studies of chromium oxide surfaces involved oxidation of low index Cr single-crystals [14][15][16][17][18][19][20][21][22][23][24][25][26][27]; surfaces of a-Cr 2 O 3 (0001) bulk crystals [28,29]; and oxidation of ultra thin films of chromium oxide grown on such transition and noble metal substrates as Pt(111) [30], Ag(111) [31], Cu(111) [32], Cu(100) [33] and Cu(110) [34] as well as on alumina [35] and W(100) [36]. Of these, only a few [15,16,28,29,31] involved quantitative surface structure determinations.…”

“…These studies are motivated to a large extent by the possibility of forming new oxide structures with new properties [37,38]. In this sense, investigation of chromium oxide growth on Pd(111) would complement previous studies of chromium oxide growth on noble and transition metal substrates [30][31][32][33][34], since there appear to be no published results for chromium oxide on Pd(111).…”

“…Chromium oxide was grown on most metal substrates [30][31][32][33][34] through thermal evaporation of chromium metal in an oxygen atmosphere. For the (111) surfaces of metal substrates, two structures relative to the substrate were observed.…”

Capacitive User Tracking Methods for Smart Environments

“…For example, the two well-known ultrasound-based location systems, Cricket [32] and Bat [53], can position a person with about 10 cm and 5 cm accuracy, respectively. Likewise, a commercial Ubisense location system based on UWB (Ultra-wideband) technology can track a person with about 15 cm accuracy [16].…”
