“…It was observed that during annealing the resistance of the film initially decreases, after which it starts to increase. This suggests that the film initially becomes a more ordered, more conductive layer, as is described in the scientific literature for various materials, 30,31 possibly through grain growth and the elimination of vacancies before it starts to dewet.…”

Au thin films of thicknesses ranging from 5 to 20 nm were grown in UHV through physical vapour deposition on glass substrates decorated with Pt interdigitated electrodes with 5 lm separation. As expected, a gradual decrease in the electrical resistance of the films was observed as growth proceeded; however, when the average film thickness was greater than around 11 nm, the resistance decrease was not smooth but occurred in discrete steps. These resistance steps are attributed to the formation of electrical percolation pathways connecting the electrodes. The samples were then annealed at temperatures between 200 C and 500 C for periods of 1 to 22 h with the aim of producing insulating nanoparticle films. Dewetting of the Au films produces nanoparticles whose size and separation depend on annealing temperature and time, as well as the initial thickness of the Au film. The complex electrical resistance behaviour of the film was also monitored during the dewetting process.

Inceptisols have problems of low availability of phosphorus. To improve soil phosphate and P fertilizer efficiency, it is necessary to develop fertilizer enriched with phosphate solubilizing bacteria (PSB). Liquid organic fertilizer enriched with PSB is expected to increase the efficiency in fertilization and improve the yield of sweet corn plants. This study was aimed to determine the effectiveness of liquid organic fertilizer enriched with Enterobacter cloacae on phosphate availability and increase the yield of maize (Zea mays L.) in Jatinangor Inceptisols. This experiment has been carried out at the Laboratory and Experimental Garden, Jatinangor, West Java, Indonesia with altitude of ±725 m above sea level. This experiment was conducted from March to September 2021. This experiment used Randomized Block Design (RBD) with three repetitions. The experiment showed the 10 L ha-1 of liquid organic fertilizer enriched with Enterobacter cloacae indigenous from Inceptisols enhanched the availability of phosphate (22,48 mg kg-1) and yield of maize (14,11 ton ha-1). Liquid organic fertilizer enriched with Enterobacter cloacae can reduced 50% of P fertilization and proposed as an alternative corn fertilizer and increased the yield of maize up to 55%, because Enterobacter cloacae to increase P solubility that caused soil available P increased.

SummaryOwing to their superior electrical characteristics, nanometer dimensions and definable lengths, single-walled carbon nanotubes (SWCNTs) are considered as one of the most promising materials for various types of nanodevices. Additionally, they can be used as either passive or active elements. To be integrated into circuitry or devices, they are typically connected with metal leads to provide electrical contacts. The properties and quality of these electrical contacts are important for the function and performance of SWCNT-based devices. Since carbon nanotubes are quasi-one-dimensional structures, contacts to them are different from those for bulk semiconductors. Additionally, some techniques used in Si-based technology are not compatible with SWCNT-based device fabrication, such as the contact area cleaning technique. In this review, an overview of the investigations of metal–SWCNT contacts is presented, including the principle of charge carrier injection through the metal–SWCNT contacts and experimental achievements. The methods for characterizing the electrical contacts are discussed as well. The parameters which influence the contact properties are summarized, mainly focusing on the contact geometry, metal type and the cleanliness of the SWCNT surface affected by the fabrication processes. Moreover, the challenges for widespread application of CNFETs are additionally discussed.
