Carbon-Based Supercapacitors Produced by Activation of Graphene

Activated microwave-exfoliated graphite oxide combined with an ionic liquid can be used to make an enhanced capacitor.

Controlled growth of SiO2 tunnel barrier and crystalline Si quantum wells for Si resonant tunneling diodes

Two methods for producing Si-oxide barriers upon which crystalline Si layers can be grown are presented. One method entails oxide island nucleation on a clean vicinal Si(001) su...

<i>In situ</i> Si flux cleaning technique for producing atomically flat Si(100) surfaces at low temperature

We have developed a method for removing oxides and producing atomically flat Si(100) surfaces with single atomic height steps using a Si flux cleaning technique. By introducing ...

Energetics of void enlargement in thermally grown ultrathin Si-oxide on Si(001)

Void formation on ultrathin thermal silicon oxide films on the Si(100) surface

The formation of voids on the thermally grown (650 °C) ultrathin (∼1 nm) silicon oxide films on the Si(100) surface was investigated by using ultrahigh vacuum scanning tunneling...
