Electrical conductivity in silicon nanomembranes
Silicon nanomembranes (SiNMs) are very thin, large, free-standing or free-floating two-dimensional (2D) single crystals that can variously be flat, rolled into tubes, or made into any number of odd shapes, cut into millions of identical wires, used as conformal sheets, or chopped into tiny pieces. Because SiNMs are mostly surface or interface and little bulk, they have very interesting properti...
متن کاملInfluence of surface properties on the electrical conductivity of silicon nanomembranes
Because of the large surface-to-volume ratio, the conductivity of semiconductor nanostructures is very sensitive to surface chemical and structural conditions. Two surface modifications, vacuum hydrogenation (VH) and hydrofluoric acid (HF) cleaning, of silicon nanomembranes (SiNMs) that nominally have the same effect, the hydrogen termination of the surface, are compared. The sheet resistance o...
متن کاملBiaxially stretchable "wavy" silicon nanomembranes.
This Letter introduces a biaxially stretchable form of single crystalline silicon that consists of two dimensionally buckled, or "wavy", silicon nanomembranes on elastomeric supports. Fabrication procedures for these structures are described, and various aspects of their geometries and responses to uniaxial and biaxial strains along various directions are presented. Analytical models of the mec...
متن کاملSilicon nanomembranes for fingertip electronics.
We describe the use of semiconductor nanomaterials, advanced fabrication methods and unusual device designs for a class of electronics capable of integration onto the inner and outer surfaces of thin, elastomeric sheets in closed-tube geometries, specially formed for mounting on the fingertips. Multifunctional systems of this type allow electrotactile stimulation with electrode arrays multiplex...
متن کاملFast flexible electronics with strained silicon nanomembranes
Fast flexible electronics operating at radio frequencies (>1 GHz) are more attractive than traditional flexible electronics because of their versatile capabilities, dramatic power savings when operating at reduced speed and broader spectrum of applications. Transferrable single-crystalline Si nanomembranes (SiNMs) are preferred to other materials for flexible electronics owing to their unique a...
