AlGaN/GaN high electron mobility transistors (HEMTs) with polar and nonpolar ZnO nanowires modified gate exhibit significant changes in channel conductance upon expose to different concentration of carbon monoxide (CO) at room temperature. The ZnO nanowires, grown by chemical vapor deposition (CVD), ...
Interestingly, room-temperature ferromagnetism is observed in both of polar (0001) c -plane and non-polar (1010) m -plane Co-doped ZnO films. As the most promising nanostructures, the assembled nanostructured Co-doped ZnO films may find future applications in spintronics devices. 展开 ...
Draw the Lewis structure for SO2. Show all lone pairs and locate any formal charges. Determine the number of valence electrons, give the overall shape of the molecule, and indicate whether the molecule is polar or nonpolar. D...

For (SF_4)^(2-): A. Draw Lewis structures B. Draw all resonance structures (if any) C. Write the correct name for the geometry D. State the difference in electronegativity between the bonding atoms E. State if the bonds are polar or nonpolar ...
Is the molecule polar or nonpolar? Draw the Lewis structure for CHCl3 and provide the following information. a. number of electron groups b. electron pair geometry c. bond angle d. number of bonded electrons e. molecular geometry f. polarity Sketch the lewis dot s...
The fluorescence solvatochromism phenomenon occurred by decreasing emission bands at 583 nm only in highly polar solvents such as DMF. A change in the PL spectra by addition of n-hexane as a nonpolar solvent or MeOH as a polar solvent to THF solution was measured to investigate this phenomenon...
