Inkjet-printed low-dimensional materials-based complementary electronic circuits on paper

Abstract

Complementary electronics has represented the corner stone of the digital era, and silicon technology has enabled this accomplishment. At the dawn of the flexible and wearable electronics age, the seek for new materials enabling the integration of complementary metal-oxide semiconductor (CMOS) technology on flexible substrates, finds in low-dimensional materials (either 1D or 2D) extraordinary candidates. Here, we show that the main building blocks for digital electronics can be obtained by exploiting 2D materials like molybdenum disulfide, hexagonal boron nitride and 1D materials such as carbon nanotubes through the inkjet-printing technique. In particular, we show that the proposed approach enables the fabrication of logic gates and a basic sequential network on a flexible substrate such as paper, with a performance already comparable with mainstream organic technology.

Fully Printed and Flexible Schottky Diodes Based on Carbon Nanomaterials Operating Up to 5 MHz

“…A commercial 99.9% semiconducting single-walled CNT toluene solution (IsoSol-S100, from NanoIntegris) with a concentration of 0.2 mg•mL −1 in toluene, and average diameter and length of the CNT of 1.4 nm and 1 µm, respectively, was used as semiconductor. A characterization of the inkjet printed network from this formulation is available in a previous work by our group [36]. Prior to printing, Kapton was washed in deionized water and dried with nitrogen.…”

Opportunities for cost-effective manufacturing of fully printed high performance displays enabled by vertical light-emitting transistor pixels

“…A variety of flexible CNT-based electronic devices (e.g. electronic circuits, sensors, displays, and nanobio devices) were fully or partially IJP fabricated using optimized ink formulations and printing conditions [78,128,129]. Although in the future the devices could be fully printed, presently, depending on the device design and material selection, the combination of conventional deposition and patterning methods with printing techniques or a combination of contact and non-contact methods are quite common.…”

Multiscale Simulations of 2-D Material Ink-Based Printed Network Devices

“…The 2-D materials represent an alternative option due to their unique features demonstrated so far, such as their high mobility, good ON-OFF ratio, atomic thickness, transparency, and flexibility [11]. Many experimental demonstrations of 2-D material-based printed devices have been recently reported [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22].…”
