Nano-mapping Material Interfaces via Hot Electrons

Goh K.E.J., Troadec C., Institute of Materials Research and Engineering, SG

As devices shrink below 100 nm in size, nanoscale imperfections (due to defects and doping) at material interfaces become significant perturbations to ideal device characteristics and in some cases can dominate the device behavior. Of [...]

Hierarchically Branched Gecko Tapes Imprinted Using Porous Alumina Templates

Yee A.H.Y., Lam Y.C., Institute of Materials Research and Engineering, SG

In this work, we show the methodology to fabricate hierarchical nano-structures of various geometrical parameters to mimic closely gecko’s adhesion system. The relevant geometrical parameters investigated are a) the aspect ratio of the fibrils b) [...]

A Hydrophobicity Controlled Nanofluidic Pump

Liu H., Dharmatilleke S., Tay A.A.O., Institute of Materials Research and Engineering, SG

interfacial energies in the system. Many methods for modulation of surface tension to manipulate fluids in micro or nano scale have been studied and reported, including the mechanical (surface roughness effect), chemical (electrochemical effect), opto- [...]

Direct observation of carbon nanostructures growth using in-situ ultrahigh vacuum transmission electron microscopy

Foo Y.L., Lin M., Tan J.P.Y., Boothroyd C.B., Tok E.S., Institute of Materials Research and Engineering, SG

The growth dynamics of single-walled carbon nanotube (SWNT) is observed in real-time using an in-situ ultra-high vacuum transmission electron microscope at 650 oC. The SWNTs preferentially grow on smaller sized catalyst particles (diameter ≤ 6 [...]
