Nanometric Structure-Property Relationship In Hafnium Oxide Thin Films Made By Sputter-Deposition, Mirella Vargas Jan 2014

Nanometric Structure-Property Relationship In Hafnium Oxide Thin Films Made By Sputter-Deposition, Mirella Vargas

Open Access Theses & Dissertations

Hafnium oxide (HfO2) is technologically an important material, which exhibits a unique set of properties such as a high dielectric constant (k~25) and wide band gap (~5.7 eV) which make this material attractive in the fields of microelectronics and optoelectronics. HfO2 has become the leading candidate to replace SiO2 dielectrics in gate oxides due to a higher permittivity and reportedly lower electron tunneling effects. HfO2 exhibits various polymorphs; the thermodynamic stability and phase existence depends on the temperature and pressure conditions. In addition, the controlled growth and manipulation of specific HfO2 crystal structures at the nanoscale dimensions is ...

Digital printing is a commonly used for small and medium run length printing. It seems to be an alternative to traditional printing systems as its print speed and quality improve each day. Printing can be done by digital printing machines using many different substrates and toners. Different color and quality results can be obtained depending on the substrates used in digital printing systems as well as in other printing systems. Substrates give different results for density and Lab values depending on their surface characteristics even if they print at the same printing conditions. Electrophotographic printing technology is one of the ...
