Electronic transport properties of mixed transition metal ions doped borophosphate glasses

Thermal, structure and morphological properties of lithium disilicate glasses doped with copper oxide and their glass–ceramic derivatives

“…3 and Table 3, the density values of lithium disilicate glasses doped with copper oxide are observed to decrease as the CuO ratio increases. The decrease of density from 2.478 to 2.367 g/cm 3 might be correlated with a change in the glass network which becomes loosely packed with increasing CuO concentration [9,10]. The density values of lithium disilicate glasses are observed to be slightly higher than the values obtained from published work [11], which can be related to the small addition of Al 2 O 3 in the glass composition causing some compaction within the structure.…”

“…On the other hand, the molar volume of the studied glasses is found to increase as the CuO content increases from 20.27 to 21.3 cm 3 /mol indicating that some structural changes may be taking place in the glass network [9].…”

Electrical conduction mechanism in polycrystalline titanium oxide thin films

“…Understanding the electronic properties of the transition-metal oxides is a precondition required in electronic device application. Many efforts have been performed in this direction [8][9][10][11][12][13][14], but the picture of the electrical transport mechanisms of these materials is not very clear yet.…”

The substrate temperature dependent electrical properties of titanium dioxide thin films

“…There are some recent attempts to understand the outstanding electronic properties of transition-metal oxides [8][9][10]. However, the picture of electrical transport mechanisms of these materials is not very clear yet, and a more profound understanding is needed.…”
