Numerical results of the Haldane gap as a function of external magnetic field concerned are presented and compared with experiment results via electron-spin-resonance technique and other theories.

A DFT study on structure,energy gap and spectrum property of the conjugated polymer poly(2,5-furylene vinylene);

The determining method for energy gap and energy-band parameters of conducting polymers;

Study on specific heat and two energy gaps of MgB_2 samplesprepared by ambient pressure and high pressure;

PAS is a semiconductor material with quite small band gap and good pristine electric conductivity.

7, which showed different band gap values.

The results indicate that, with compressibility increasing , the width of band gap becomes wider,and that the interaction between Fe d electrons and S p electrons is stronger,and length of Fe-S bond becomes shorter.

A Precise CMOS Bandgap Voltage Reference;

A new low-voltage bandgap voltage reference was presented.

Based upon analysis of several type s of bandgap voltage reference circuit, we demonstrate a high precision circuit of bandgap voltage reference with relatively simple structure for high-speed se rial link.
