“…The source-, drain-, and gate electrodes were all thermally evaporated at a pressure of approximately 10 mbar. Further details on the transistor fabrication processes and electronic properties of the reference ÅA transistor can be found from our previous publications[6,[27][28][29]. All transistor devices were fabricated and measured in a nitrogen atmosphere.…”

Cellulose nano-and microfibrils (CNF/CMF) grades vary significantly based on the raw materials and process treatments used. In this study four different CNF/CMF grades were combined with kaolin clay pigment particles to form nanoporous composites. The attained composite properties like porosity, surface smoothness, mechanical properties and density properties depended strongly on the raw materials used. In general, higher kaolin content (∼80 wt%) led to controllable shrinkage during drying, which resulted in improved dimensional stability of composites, compared to a lower kaolin content (∼50 wt%). On the other hand, the use of a plasticizer and a high amount of CNF/CMF was essential to produce adequate elasticity for the composites. The performance of transistors when fabricated on the nanoporous composites was strongly dependent on the raw materials used. The formation of the semiconductor layer was affected by the porosity, roughness, hydrophobicity, polarity and absorption properties of the top-most layer at the composite. The developed natural fiber-based substrates may be applied to novel value-added applications in intelligent products, such as sensors and simple displays.

“…[57] Encapsulation was shown to be necessary to preserve transistors from degradation when exposed to water vapours. [38,39] Conversely, a barrier layer would not be advantageous in CNTs based supercapacitors: CNTs functionalized Xerox paper revealed better performances and stability than PET with the same functionalization, since the CNTs layer is easily peeled off from PET, while it sticks much more strongly on paper surface, yielding devices with high operational stability. [48] In this case, only encapsulation of the device would be necessary.…”

“…Some coating materials, like plastics, organometallics or metal oxides, are clearly not biodegradable or can even be toxic. Conversely, some of the most recent coating strategies that have been developed are carried out by using sustainable and biodegradable starting materials [8,37,73,38,39,46,47,49,66,67,70] . In most cases, the method proposed for the easy disposal of the devices at the end of their lifetime is incineration, that would destroy the organic material.…”

Paper is a flexible material, commonly used for information storage, writing, packaging or specialized purposes. It also has strong appeal as a substrate in the field of flexible printed electronics. Many applications, including safety, merchandising, smart labels/packing, chemical/biomedical sensors, require an energy source to power operation. Here we review progress regarding development of photovoltaic and energy storage devices on cellulosic substrates where one or more of the main material layers are deposited via solution processing or printing. Paper can be used simply as the flexible substrate or, exploiting its porous fibrelike nature, as an active film by infiltration or co-preparation with electronic materials. Solar cells with efficiencies of up to  4% on opaque and 9% on transparent substrates have been demonstrated. Recent developments in paper-based supercapacitors and batteries are also reviewed with maximum achieved capacity of 1350 mF cm -2 and 2000 mAh g -1 respectively.Analysing the literature, it becomes apparent that more work needs to be carried out in continuing to improve peak performance, but especially stability and the application of printing techniques, even roll-to-roll, over large areas. Paper is not only environmentally friendly and recyclable, it is thin, flexible, low-weight, biocompatible, and low-cost.

“…A linear dependency of V On on V GS2 was verified, both in linear and saturation regime, as shown in Figure 4 When there is no voltage applied at G 2 , V On is shifted towards high negative voltages (from nearly −7 V to around −25 V) just by changing the V DS from 1 to 15 V (Figure 3a), associated with the increase of the Off current by about one order of magnitude. Ionic displacement in the paper and the establishment of a charge neutrality condition that lead to the formation of the EDL at the channel and floating gate interfaces (see Figure 5) [31] are responsible for the operation mode as well as the maximum and minimum source to drain current.…”

topic along the last decade. [1][2][3][4] Paper's basic unit is cellulose, which is the most abundant biopolymer on earth; it is a lowcost material (≈10 −3 cent m −2 ), lightweight, flexible, and 100% recyclable. Moreover, the nearly 100 million tons produced per year using roll-to-roll processing with speed of about 30 m s −1 turns paper and cellulose-based materials highly attractive to serve the pushing demands for the new era of low-cost disposable and recyclable large area electronics for concepts such as Internet-of-Things (IoT), with a strong future societal impact. [5][6][7][8][9][10] From the commercial point of view, the use of paper in "electronics" has been mostly limited to separator membranes in passive electronic components such as capacitor batteries, or simply as a substrate for hybrid radio-frequency identification (RFID) tags. Even if still looking for real market implantation, it has been demo nstrated that paper can also be used as a platform for microfluidics and sensors, energy storage devices, organic thin film transistors (OTFTs), printed batteries, or even foldable printed circuit boards. [11][12][13] The exploration of paper as a genuinely electronic material has been demonstrated for the first time in our past work, where it was used as gate dielectric in field effect transistors (FETs), [9,[14][15][16] write-erase and read memory transistors (WERM-FETs), [17] solidstate paper batteries, [18] and inverters. [19] These reports demonstrate that paper offers an eclectic range of applications as substrate or as an active part in devices, enabling a new generation of low-cost and disposable analogue and digital electronic circuits. [20] In this work, we go further in exploring paper as the gate dielectric by implementing it on dual-gate in-plane oxide-based FETs with a back floating gate electrode (DG-FGFETs) enabling multilogic functionalities. Although the concept of dual-gate FET has been already tested on Si technology with SiO 2 -based gate dielectrics, [21,22] it is now proposed on paper, which is simultaneously explored as the substrate and solid-state electrolyte relying on the electric double layer (EDL) formation. This concept has also been used with organic semiconductors on paper surfaces, [21] and even with other ionic dielectrics, as chitosan or alginate, to create artificial synapses to emulate biological synaptic functions, which are often referred to as synaptic transistors in the literature. [22,23] However, the on-voltage (V On ) modulation through the second gate and the ability to perform logic operations with these devices has not been thoroughly reported using oxides Electronics on paper enable some specific applications out of conventional ones which require innovative approaches and concepts on the design of devices and systems. Within this context, this work demonstrates that a unique set of characteristics can be combined in planar dual-gate oxide-based field effect transistors with a back floating electrode using paper simultaneously as substrate and dielectric. ...
