Effect of carbon nanotube pillar arrays' edge effect on field emission characteristics is first studied. The ratio of field emission current density at 5.733V/μm is about 55: 6.5: 1 which is nearly proportional to the edge ratio (50:5:1) for small, middle, and large sizes of CNTs' arrays. Besides, ultra low turn-on field (~1.4 V/μm), well emission image uniformity and stability of about ±6.52 % at...
The inverted bulk hetero-junction solar cell on the polyester (PET) substrate with a non-annealing active layer is investigated. Our investigations show that the easily processed inverted device with a non-annealing active layer on the indium-tin-oxide coated PET substrate exhibits a high power conversion efficiency of ~3.65%.
Low temperature processes are the better ways to integrate carbon nanotubes (CNTs) with CMOS chips into array-type gas sensors. Almost the metal used in CMOS is Al-Si-Cu alloy, which make the sustainable temperature of CMOS structures be in the range of 400- 500degC. We offer a new fabrication method of CNTs-based gas sensors at low temperature. The oxidized silicon substrate was modified with 3-aminopropyltriethoxysilane...
In this paper, we investigated the self-cleaning effects of biomimetic dry adhesives, which are made of e-beam photoresist and carbon nanotubes (CNT). Although the photoresist and the CNT are both intrinsically hydrophilic, superhydrophobic behavior was obtained when they were patterned or synthesized into nano-fibrils. The intrinsic hydrophilicity indicates that these materials possess sufficient...
