Until now, few sp(2) carbon materials simultaneously exhibit superior performance for specific surface area (SSA) and electrical conductivity at bulk state. Thus, it is extremely important to make such materials at bulk scale with those two outstanding properties combined together. Here, we present a simple and green but very efficient approach using two(More)
We present a new process to get in-situ-growth carbon nanotubes (CNTs) array device with good FE properties by CO2-assisted thermal chemical vapor deposition (CVD). Field Emission measurement shows that introducing CO2 into CNTs growth system leads to a significant enhancement in the emission properties, both the turn-on field and threshold field decrease.(More)
