Tuning Of Magnetization In Vertical Graphenes By Plasma-Enabled Chemical Conversion Of Organic Precursors With Different Oxygen Content, Zengji Yue Dec 2012

Tuning Of Magnetization In Vertical Graphenes By Plasma-Enabled Chemical Conversion Of Organic Precursors With Different Oxygen Content, Zengji Yue

Zengji Yue

Different magnetization in vertical graphenes fabricated by plasma-enabled chemical conversion of organic precursors with various oxygen atom contents and bonding energies was achieved. The graphenes grown from fat-like precursors exhibit magnetization up to 8 emu g−1, whereas the use of sugar-containing precursors results in much lower numbers. A relatively high Curie temperature exceeding 600 K was also demonstrated.


Structural, Optical And Electrical Properties Of Europium Picrate Tetraethylene Glycol Complex As Emissive Material For Oled, Wan Haliza Abd Majid Dec 2011

Structural, Optical And Electrical Properties Of Europium Picrate Tetraethylene Glycol Complex As Emissive Material For Oled, Wan Haliza Abd Majid

Wan Haliza binti Abd Majid

A new europium complex [Eu(Pic) 2(H 2O)(EO4)](Pic) ·0.75H 2O was synthesized and used as the emission material for the single layer device structure of ITO/EO4EuPic/Al, using a spin-coating technique. Study on the optical properties of the [Eu(Pic) 2(H 2O)(EO4)](Pic)·0.75H 2O complex where EO4=tetraethylene glycol and Pic=picrate anion, had to be undertaken before being applicable to the study of an organic light emitting diode (OLED). The electrical property of an OLED using currentvoltage (IV) measurement was also studied. In complex, the Eu(III) ion was coordinated with the EO4 ligand as a pentadentate mode, one water molecule, and with two Pic anions …


Synthesis, Magnetic Properties And X-Ray Analysis Of Zn0.97x0.03o Nanoparticles (X = Mn, Ni, And Co) Using Scherrer And Size-Strain Plot Methods, Wan Haliza Abd Majid Dec 2011

Synthesis, Magnetic Properties And X-Ray Analysis Of Zn0.97x0.03o Nanoparticles (X = Mn, Ni, And Co) Using Scherrer And Size-Strain Plot Methods, Wan Haliza Abd Majid

Wan Haliza binti Abd Majid

Un-doped and doped ZnO nanoparticles (Zn0.97X0.03O-NPs, X = Mn, Co, and Ni) were synthesized from a metal acetate precursor and acetic acid by a modified sol gel combustion method. The compounds were synthesized at calcination temperatures of 650 degrees C for 1 h. The synthesized un-doped/doped ZnO-NPs were characterized by X-ray diffraction analysis (XRD) and high-magnification transmission electron microscopy (TEM). The XRD results revealed that the sample product was crystalline with a hexagonal wurtzite phase. The TEM showed ZnO-NPs nearly spherical shapes and a non-uniform shape for doped ZnO-NPs. The crystalline development in the ZnO-NPs was investigated by X-ray peak …


Angular-Dependences Of Giant In-Plane And Interlayer Magnetoresistances In Bi2te3 Bulk Single Crystals, Zengji Yue Dec 2011

Angular-Dependences Of Giant In-Plane And Interlayer Magnetoresistances In Bi2te3 Bulk Single Crystals, Zengji Yue

Zengji Yue

Angular-dependences of in-plane and interlayer magnetotransport properties in n-type Bi2Te3 bulk single crystals have been investigated over a broad range of temperatures and magnetic fields. Giant in-plane magnetoresistances (MR) of up to 500% and interlayer MR of up to 200% were observed, respectively. The observed MR exhibits quadratic field dependences in low fields and linear field dependences in high fields. The angular dependences of the MR represent strong anisotropy and twofold oscillations. The observed angle-dependent, giant MR might result from the strong coulomb scattering of electrons as well as impurity scattering in the bulk conduction bands of n-type Bi2Te3. The …
