High‐Performance n‐Channel Printed Transistors on Biodegradable Substrate for Transient Electronics

Abstract

However, due to the poor charge carrier mobility, these electronic circuits do not match the performance of conventional integrated circuits (ICs) and as a result, their application is restricted to the low-end. High performance is much needed to drive advances in nearly all conventional and emerging application areas of electronics including connected systems, Industry 4.0, digital healthcare, digital agriculture, interactive systems, etc., where high-speed electronics is required to reduce the data latency. [3] In this regard, nanostructures such as nanowires, [4] nanoribbons (NRs), [5] etc. and thin films of high-mobility inorganic materials offer a viable alternative. Their performance is on par with conventional silicon-based devices, and they can also be dissolved or disintegrated in controlled environments (Table 1). [1e,1f,6]

Layer-by-layer thinning of two-dimensional materials

“…In this regard, researchers have explored various new semiconductor materials, aiming to keep surpassing the performance of Sibased devices. [6][7][8][9][10] M. Vasundhara M. Vasundhara is presently working as a Principal Scientist at CSIR-Indian Institute of Chemical Technology (CSIR-IICT), as an associate professor in the Academy of Scientific and Innovative Research (AcSIR), Hyderabad. She received her PhD (Experimental Condensed Matter Physics) from the Indian Institute of Technology Kharagpur.…”

“…In this regard, researchers have explored various new semiconductor materials, aiming to keep surpassing the performance of Sibased devices. [6][7][8][9][10] requires precise control over the layer numbers and shapes of these 2D materials, making it imperative to employ techniques for thinning them down. For instance, conventional graphene is typically grown on metal substrates using the chemical vapor deposition (CVD) method.…”

Inkjet Printing of Aqueous Silver Inks on Water-Soluble Fabrics for Transient Electronics Applications

“…19 Other routes involved the fabrication of the necessary patterns on a donor substrate using conventional lithographic processes followed by solid-state transfer printing. 20 Laser-induced evaporation of metals was also utilized for the patterned transfer of metallic features. 21 These approaches have been instrumental for demonstrating the proof of the concept; however, they have limitations regarding mechanical placement of stencil masks and donor substrate, eventually leading to issues in terms of reproducibility, resolution, and practicality.…”

Printed n- and p-Channel Transistors using Silicon Nanoribbons Enduring Electrical, Thermal, and Mechanical Stress

“…Printed electronics is rapidly changing the way electronics is manufactured and used. − With resource-efficient and low-cost fabrication of electronics over large areas (larger than the commercially available wafers) and flexible and stretchable substrates, the printed electronics is advancing several applications. ,− Efficient use of various materials also makes printing attractive in terms of lower electronic waste (e-waste) and better environment friendliness. − ,− As a result, the printing technologies have been explored for devices such as artificial thermoreceptors, touch sensors, synaptic transistors, energy harvesters, − radio frequency identification (RFID) tags, and interconnects, etc. needed in conformable and interactive electronic systems. ,, However, the nonavailability of high-performance (i.e., low power, fast speed) processing units has restricted the utility of printed electronics to low-end applications.…”
