Femtosecond time-resolved study in InxGa1-xN (0001) ultrathin epilayers: Effects of high indium mole fraction and thickness of the films
(2006)In view of promising full-solar-spectrum photovoltaic systems based on Inx Ga1-x N ternary alloys, femtosecond time-resolved study in ultrathin epilayers was employed in order to extract the fundamental properties of ...

Indium oxide as a possible tunnel barrier in spintronic devices
(2005)We report the growth of ultra-thin indium oxide layers using the dc-magnetron sputtering method. We demonstrate that good quality tunnel barriers made of indium oxide can be routinely fabricated and employed in spintronic-related ...

Time-resolved ultrafast carrier dynamics in as-grown nanocrystalline silicon films: The effect of film thickness and grain boundaries
(2008)In this letter, we have studied transient photoinduced absorption in as-grown nanocrystallinc silicon films with thickness varied from 5 to 30 nm. Effects of quantum confinement (QC) in z-direction and grain boundary ...

Transient photoinduced absorption in ultrathin as-grown nanocrystalline silicon films
(2008)We have studied ultrafast carrier dynamics in nanocrystalline silicon films with thickness of a few nanometers where boundary-related states and quantum confinement play an important role. Transient non-degenerated ...
