“…Synthesizing nanomaterials onto silicon substrates is attracting much attention. [19][20][21][22][23] One key reason is that once nanomaterials are synthesized onto silicon substrates, it is straightforward to integrate the nanomaterials with silicon based electronic circuits to achieve functional devices. Furthermore, the Co 3 O 4 nanowalls and nanowires fabricated onto Co foil substrates are not firmly attached to the substrate (easy to be peeled off).…”

Co 3 O 4 nanowalls and nanowires have been synthesized onto silicon substrates by low-temperature thermal oxidation of sputtered Co thin films in static air. The synthesis method is very simple and suitable for large-scale fabrication. The effects of the thermal oxidation temperature and duration on the size, amount, and length of the nanowires and nanowalls are systematically investigated both by scanning electron microscopy characterization and differential scanning calorimetry thermal analysis. It is found that the Co/CoO oxidation and Co 3 O 4 decomposition are important factors contributing to the growth of the Co 3 O 4 nanowalls and nanowires. The mechanical adhesion between the Co 3 O 4 nanowalls/nanowires/film and the silicon substrate is observed to be very strong, which is beneficial for many practical applications. Based on the experimental observations, the detailed growth mechanisms of the nanowalls and nanowires are presented. Finally, the promising novel exothermic reaction properties of the Co 3 O 4 nanowalls and nanowires with Al are investigated by thermal analysis. V C 2012 American Institute of Physics. [http://dx.

“…In FEF, the heat source is provided by the electric voltage. FEF can be explained as follows: (a) micro/nano heater, connected to a constant electric current, is immersed in aqueous ZnO precursors for increasing the temperature at the desired hot spot; (b) by endothermal reaction, nanomaterials are synthesized at local heated spots until the electric power is disconnected [ 24 , 66 , 67 ].…”

“…Among various wet chemical methods, the hydrothermal process is regarded as one of the most attractive methods for ZnO fabrication as it is facile to set up and is controllable, cost-effective, relatively low temperature and an environment benign process [ 39 , 48 , 64 , 65 ]. Many different approaches such as resistive nano heater [ 24 , 66 , 67 ], bulk heating [ 61 , 68 ], microcontact printing [ 17 , 63 , 69 , 70 , 71 ], inkjet printing [ 17 , 57 , 62 , 72 , 73 ] and laser-induced heating [ 44 , 46 , 61 , 68 , 74 , 75 ] have been developed via the hydrothermal method. These approaches require different setups, processing factors and also different ways for required factors.…”

Ultraviolet (UV) sensors offer significant advantages in human health protection and environmental pollution monitoring. Amongst various materials for UV sensors, the zinc oxide (ZnO) nanostructure is considered as one of the most promising candidates due to its incredible electrical, optical, biomedical, energetic and preparing properties. Compared to other fabricating techniques, hydrothermal synthesis has been proven to show special advantages such as economic cost, low-temperature process and excellent and high-yield production. Here, we summarize the latest progress in research about the hydrothermal synthesis of ZnO nanostructures for UV sensing. We particularly focus on the selective hydrothermal processes and reveal the effect of key factors/parameters on ZnO architectures, such as the laser power source, temperature, growth time, precursor, seeding solution and bases. Furthermore, ZnO hydrothermal nanostructures for UV applications as well as their mechanisms are also summarized. This review will therefore enlighten future ideas of low-temperature and low-cost ZnO-based UV sensors.

“…Similar lithography-free techniques have also been proposed for sensor applications [13], study of biological and chemical phenomena [14], catalytic NW growth [15], and selective removal of metallic CNTs [16]. Localized heating has also been used as a simple patterning approach for nanoscale positioning [17][18][19]. Microheaters have been studied for selective functionalization of sensors [20] and catalytic synthesis of nanomaterials [18].…”

SANTA: Self-aligned nanotrench ablation via Joule heating for probing sub-20 nm devices

et al. 2016

Manipulating materials at the nanometer scale is challenging, particularly if alignment with nanoscale electrodes is desired. Here we describe a lithography-free, self-aligned nanotrench ablation (SANTA) technique to create nanoscale "trenches" in a polymer like poly(methyl) methacrylate (PMMA). The nanotrenches are self-aligned with carbon nanotube (CNT) and graphene ribbon electrodes through a simple Joule heating process. Using simulations and experiments we investigate how the Joule power, ambient temperature, PMMA thickness, and substrate properties can improve the spatial resolution of this technique. We achieve sub-20 nm nanotrenches for the first time, by lowering the ambient temperature and reducing the PMMA thickness. We also demonstrate a functioning nanoscale resistive memory (RRAM) bit self-aligned with a CNT control device, achieved through the SANTA approach. This technique provides an elegant and inexpensive method to probe nanoscale devices using self-aligned electrodes, without the use of conventional alignment or lithography steps.
