Organic–Inorganic Hybrid Interfaces for Spin Injection into Carbon Nanotubes and Graphene

Fully Polarized Spin Injection into Carbon Nanotubes

Appropriately doped perovskite oxides of manganese such as La2/3Sr1/3MnO3 (LSMO) are ferromagnetic metals in which the conduction electrons tend to be 100% spin polarised [5]. It is therefore desirable to fabricate CNT devices with LSMO electrodes. However, to integrate these two very different material systems into a single device is challenging since their growth conditions are potentially mu...

Twisting graphene nanoribbons into carbon nanotubes

Although carbon nanotubes consist of honeycomb carbon, they have never been fabricated from graphene directly. Here, it is shown by quantum molecular-dynamics simulations and classical continuum-elasticity modeling, that graphene nanoribbons can, indeed, be transformed into carbon nanotubes by means of twisting. The chiralities of the tubes thus fabricated can be not only predicted but also ext...

Low-resistance spin injection into silicon using graphene tunnel barriers.

Spin manipulation in a semiconductor offers a new paradigm for device operation beyond Moore's law. Ferromagnetic metals are ideal contacts for spin injection and detection, but the intervening tunnel barrier required to accommodate the large difference in conductivity introduces defects, trapped charge and material interdiffusion, which severely compromise performance. Here, we show that singl...

Carbon nanotubes and graphene towards soft electronics

Although silicon technology has been the main driving force for miniaturizing device dimensions to improve cost and performance, the current application of Si to soft electronics (flexible and stretchable electronics) is limited due to material rigidity. As a result, various prospective materials have been proposed to overcome the rigidity of conventional Si technology. In particular, nano-carb...
