Tin oxide nanowires: The influence of trap states on ultrafast carrier relaxation
(2009)We have studied the optical properties and carrier dynamics in SnO 2 nanowires (NWs) with an average radius of 50 nm that were grown via the vapor-liquid solid method. Transient differential absorption measurements have ...

Ultrafast pulsed laser deposition of carbon nanostructures: Structural and optical characterization
(2013)Carbon nanostructured materials were obtained by high-repetition rate pulsed laser ablation of a graphite target using a train of 10-ps duration pulses at 1064 nm in different pressures of high-purity Ar gas. It is ...

Ultrafast time-resolved spectroscopy of Si nanocrystals embedded in SiO2 matrix
(2009)In this work, we present a comprehensive study of ultrafast transient photoinduced absorption of silicon nanocrystals (NCs) embedded in SiO2 matrix. The samples under investigation are single monolayers of Si-NCs embedded ...

Ultrafast transient photoinduced absorption in silicon nanocrystals: Coupling of oxygen-related states to quantized sublevels
(2007)The authors have studied transient photoinduced absorption in single monolayers of oxidized silicon nanocrystals. Transient photoinduced absorption measurements along with optical absorption and photoluminescence (PL) ...

Verification of initial-state opacity in security applications of DES
(2008)Motivated by security applications where the initial state of a system needs to be kept secret (opaque) to outside observers (intruders), we formulate, analyze and verify the notion of initial-state opacity in discrete ...

Zn3N2nanowires: Growth, properties and oxidation
(2013)Zinc nitride (Zn3N2) nanowires (NWs) with diameters of 50 to 100 nm and a cubic crystal structure have been grown on 1 nm Au/Al2O3via the reaction of Zn with NH3including H2between 500°C and 600°C. These exhibited an optical ...
