It is observed that a significant decrease in band gap of NiO was noticed. Surface morphological study was carried out by using FESEM, which revealed the transformation of sheet like structures of [Ni(OH)2] to polyhedral shaped NiO on calcination. The presence of nickel and oxygen was ...
The band gap of NiO film widened significantly owing to Mn doping. Urbach energy was estimated using absorbance data. The highest room-temperature resistivity observed for 2 at% Mn-doped NiO film was 2.01×105Ω-cm. The 2 at% Mn-doped NiO film had the minimum activation energy (0.12 eV)...

During the calculation of the energy band gap, it is found that all nanocomposite have redshifted energy band gaps. (As a result, the energy band gap decreased to 4.09 eV, 4.49 eV, and 4.73 eV for nanocomposites of PS/Al, PMMA/Al, and PVA/Al respectively. The PS/Ag, PMMA/Ag, and...
We have investigated the structural, optical band gap, and electrical properties of (Fe2O3)0.5x:(NiO)1 − 0.5x (x = 0.3, 0.4, 0.5, 0.6 and 0.7) epitaxial thin films grown on an atomically smooth substrate at room temperature. With increasing Fe2O3 content, the rock-salt ...
A noticeable decrease in the optical energy band gap at 0.4 wt% of NiO nanofiller and 1.0 wt% of CuO nanofiller loading, attributed to reduced crystallinity, which is confirmed by XRD results. PALS measurements reveales the presence of bigger free volume holes, which facilitate dipole ...
band gap + 添加翻译 英文-西班牙文字典 Banda prohibida energy range in a solid where no electron states can exist; energy difference (in electron volts) between the top of the valence band and the bottom of the conduction band in insulators and semiconductors Because, you know, we were ...
It is known that the PBE functional underestimates the band gap of silicon. To obtain the electronic band structure with correct gap, other method and functional are used for silicon, e.g., the many-body perturbation theory based on the GW approximation31,32 and the hybrid functional proposed...
