Improved Drain Current Saturation and Voltage Gain in Graphene-on-Silicon Field Effect Transistors.

Scientific reports

Song SM, Bong JH, Hwang WS, Cho BJ.
PMID: 27142861
Sci Rep. 2016 May 04;6:25392. doi: 10.1038/srep25392.

Graphene devices for radio frequency (RF) applications are of great interest due to their excellent carrier mobility and saturation velocity. However, the insufficient current saturation in graphene field effect transistors (FETs) is a barrier preventing enhancements of the maximum...

Structure evolution in "114" oxides CaBaZn₂Ga(2-x)Al(x)O₇ (x = 0, 1, 2) and layered cationic ordering in tetrahedral sites for CaBaZn₂Al₂O₇.

Dalton transactions (Cambridge, England : 2003)

Jiang P, Gao W, Cong R, Yang T.
PMID: 25726957
Dalton Trans. 2015 Apr 07;44(13):6069-74. doi: 10.1039/c5dt00491h.

Rietveld refinements were performed on CaBaZn2Ga(2-x)Al(x)O7 (x = 0, 1, 2) to investigate the site preference of cations in tetrahedral cavities. Tri-valent Ga(3+)/Al(3+) preferred the tetrahedral sites (T1-sites) within the triangular layers. Moreover, a layered type cationic ordering was...

High-responsivity vertical-illumination Si/Ge uni-traveling-carrier photodiodes based on silicon-on-insulator substrate.

Scientific reports

Li C, Xue C, Liu Z, Cong H, Cheng B, Hu Z, Guo X, Liu W.
PMID: 27279426
Sci Rep. 2016 Jun 09;6:27743. doi: 10.1038/srep27743.

Si/Ge uni-traveling carrier photodiodes exhibit higher output current when space-charge effect is overcome and the thermal effects is suppressed. High current is beneficial for increasing the dynamic range of various microwave photonic systems and simplifying high-bit-rate digital receivers in...

J Phys Chem A. 2014 May 15;118(19):3402-9. doi: 10.1021/jp411411j. Epub 2014 May 06.

We first demonstrate the photoelectron spectroscopic evidence of the transition of two competitive solvation patterns in the Au(-)(CH3OH)n (n = 1-5) clusters. Quantum chemical calculations have been carried out to characterize the geometric structures, energy properties and hydrogen-bonded patterns,...
