| 1 | Charge Transport in Disordered Graphene-Based Low Dimensional Materials显示文摘Two-dimensional graphene,carbon nanotubes,and graphene nanoribbons represent a novel class of low dimensional materials that could serve as building blocks for future carbon-based nanoelectronics.Although these systems share a similar underlying electronic structure,whose exact details depend on confi nement effects,crucial differences emerge when disorder comes into play.In this review,we consider the transport properties of these materials,with particular emphasis on the case of graphene nanoribbons.After summarizing the electronic and transport properties of defect-free systems,we focus on the effects of a model disorder potential(Anderson-type),and illustrate how transport properties are sensitive to the underlying symmetry.We provide analytical expressions for the elastic mean free path of carbon nanotubes and graphene nanoribbons,and discuss the onset of weak and strong localization regimes,which are genuinely dependent on the transport dimensionality.We also consider the effects of edge disorder and roughness for graphene nanoribbons in relation to their armchair or zigzag orientation. | Alessandro Cresti Norbert Nemec Blanca Biel Gabriel Niebler François Triozon Gianaurelio Cuniberti Stephan Roche | 2008 | Nano Research2008，1，5： | 10 |

| 4 | Emerging properties of non-crystalline phases of graphene and boron nitride based materials显示文摘We review recent developments on the synthesis and properties of two-dimensional materials which, although being mainly of an sp^(2) bonding character, exhibit highly disordered, non-uniform and structurally random morphologies. The emergence of such class of amorphous materials, including amorphous graphene and boron nitride, have shown superior properties compared to their crystalline counterparts when used as interfacial films. In this paper we discuss their structural,vibrational and electronic properties and present a perspective of their use for electronic applications. | Aleandro Antidormi Luigi Colombo Stephan Roche | 2022 | Nano Materials Science2022，4，1： | 1 |

| 9 | Quantum Transport Properties of Chemically Functionalized Long Semiconducting Carbon Nanotubes显示文摘We present a first-principles study of the electronic transport properties of micrometer long semiconducting carbon nanotubes randomly covered with carbene functional groups. Whereas prior studies suggested that metallic tubes are hardly affected by such addends, we show here that the conductance of semiconducting tubes with standard diameter is, on the contrary, severely damaged. The configurational-averaged conductance as a function of tube diameter, with a coverage of up to one hundred molecules, is extracted. Our results indicate that the search for a conductance-preserving covalent functionalization route remains a challenging issue. | Alejandro Lopez-Bezanilla Xavier Blase Stephan Roche | 2010 | Nano Research2010，3，4： | 0 |
| 10 | 用CPLD实现步进电机驱动器显示文摘本设计实例基于摩托罗拉(现为飞思卡尔)广为使用但已淘汰的SAA1042步进电机驱动器JC,用一片CPLD(复杂可编程逻辑器件)实现了步进电机驱动器.它也可以代替基于SAA1027或UCN5804B设计中的驱动器。本设计只使用了Xilinx XC9536CPLD中的6个宏单元,因此可以在一个小容量CPLD中实现多个步进电机驱动器。CPLD步进电机驱动器需要时钟、方向、步长和复位输入。时钟输入接受逻辑电平脉冲.并在脉冲正沿上有效。 | Stephan Roche | 2007 | 电子设计技术 EDN CHINA2007，14，5： | 0 |
