The room temperature scanning Hall probe microscopy (RT-SHPM) imaging of permalloy microstructures and garnet films was discussed. The high performance InSb Hall sensors were used for this purpose. It was shown that the InSb Hall probes were highly sensitive and low noise alternatives to GaAs sensors for RT-SHPM.

RT-SHPM imaging of permalloy microstructures and garnet films using new high performance InSb sensors
Kaval, M.; Oral, Ahmet; Dede, M.; Sandhu, A. (2002-01-01)
Scanning Hall probe microscopy (SHPM) is a quantitative and noninvasive technique to image magnetic samples with high spatial and magnetic field resolution: ∼120 nm & 6×10-6T/√(Hz) at room temperature. A sub-micron Hall probe is scanned over the sample surface to measure the surface magnetic fields using conventional scanning tunneling microscopy-positioning techniques. We have developed new low noise, high performance InSb Hall sensors for room temperature scanning Hall probe microscopy (RT-SHPM), which ha...
Temperature-dependent optical properties of GaSe layered single crystals
Hasanlı, Nızamı (2016-8-01)
Optical properties of GaSe single crystals have been investigated using temperature-dependent transmission and room temperature reflection measurements in the wavelength range of 380–1100 nm. The analysis of the absorption data at room temperature showed the existence of indirect transitions in the crystal with energy band gap of 1.98 eV. Temperature dependence of the transmission measurements revealed the shift of the absorption edge toward lower energy as temperature is increased from 10 to 280 K. The rat...
Investigation of photovoltaic properties of amorphous InSe thin film based Schottky devices
Yilmaz, K.; Parlak, Mehmet; Ercelebi, C. (IOP Publishing, 2007-12-01)
In this study, device behavior of amorphous InSe thin films was investigated through I-V, C-V and spectral response measurements onto SnO2/p-InSe/metal Schottky diode structures. Various metal contacts such as Ag, Au, Al, In and C were deposited onto amorphous p-InSe films by the thermal evaporation technique. The best rectifying contact was obtained in a SnO2/p-InSe/Ag Schottky structure from I-V measurements, while the Au contact had poor rectification. Other metal contacts (Al, In and C) showed almost oh...

Optical properties of Cu3In5S9 single crystals by spectroscopic ellipsometry
Işık, Mehmet; Nasser, H.; Ahmedova, F.; Guseinov, A.; Hasanlı, Nızamı (2018-01-01)
Cu3In5S9 single crystals were investigated by structural methods of x-ray diffraction and energy dispersive spectroscopy and optical techniques of ellipsometry and reflection carried out at room temperature. The spectral dependencies of optical constants; dielectric function, refractive index and extinction coefficient, were plotted in the range of 1.2-6.2 eV from ellipsometric data. The spectra of optical constants obtained from ellipsometry analyses and reflectance spectra presented a sharp change around ...
