摘要:

纸有望在物联网或一次性电子产品等应用中取代硅衬底,这些应用需要超低成本的电子元件和环保的电子废物管理。在过去的几年中,受到纸作为基底的上述性质以及范德华(vdW)材料的特殊电子、机械和光学性质的刺激,许多研究小组致力于将基于vdW材料的器件集成在纸上。最近,已经提出了一种通过简单地将vdW晶体摩擦纸的粗糙表面来在纸上沉积致密堆积的vdW材料互连的连续膜的方法。该方法利用弱的层间vdW相互作用,并允许通过对纸的磨损将晶体分裂成微片晶。在这里,我们的目的是说明一般的字符和这种技术的潜力,通过制造薄膜的39种不同的VDW材料(包括超导体,半金属,半导体和绝缘体)的标准复印纸。我们已经彻底表征了它们的光学性质,显示出它们的高光学质量:人们可以很容易地解决半导体vdW材料的吸收带边,甚至在一些具有高激子结合能的vdW材料中存在的激子特征。我们还测量了几种VDW材料薄膜在纸上的电阻率,发现异常低的值,这在某些情况下,数量级低于喷墨印刷生产的类似薄膜的报告。最后,我们展示了制造的场效应器件与VDW材料在纸上使用的纸基板作为离子门。

英文摘要:

Paper holds the promise to replace silicon substrates in applications like internet of things or disposable electronics that require ultra-low-cost electronic components and an environmentally friendly electronic waste management. In the last years, spurred by the abovementioned properties of paper as a substrate and the exceptional electronic, mechanical and optical properties of van der Waals (vdW) materials, many research groups have worked towards the integration of vdW materials-based devices on paper. Recently, a method to deposit a continuous film of densely packed interconnects of vdW materials on paper by simply rubbing the vdW crystals against the rough surface of paper has been presented. This method utilizes the weak interlayer vdW interactions and allows cleaving of the crystals into micro platelets through the abrasion against the paper. Here, we aim to illustrate the general character and the potential of this technique by fabricating films of 39 different vdW materials (including superconductors, semi-metals, semiconductors, and insulators) on standard copier paper. We have thoroughly characterized their optical properties showing their high optical quality: one can easily resolve the absorption band edge of semiconducting vdW materials and even the excitonic features present in some vdW materials with high exciton binding energy. We also measured the electrical resistivity for several vdW materials films on paper finding exceptionally low values, which are in some cases, orders of magnitude lower than those reported for analogous films produced by inkjet printing. We finally demonstrate the fabrication of field-effect devices with vdW materials on paper using the paper substrate as an ionic gate.
