In this paper, we describe simulations of highly rectifying carbon/p‐Si junctions using Sentaurus TCAD from Synopsys. 2‐D and 3‐D models were constructed and optimized to fit I‐V characteristics measured from these junctions. The TCAD models included a resistive interface layer, previously observed experimentally. From the model, the interface resistance was determined to be 0.04 Ω·cm2, and the work function of the graphitic contacts was determined to be 4.43 eV. The latter is the work function at the interface, which cannot be measured experimentally. Schottky barrier lowering was implemented in the model to provide agreement with the measurements. The modeling provided information that could not be obtained from measurements and suggested a path to improved devices.

“…Over the recent years, graphene has been investigated for applications in microelectronic. And due to their low specific resistivity, graphene is used for applications in interconnects as well [1]. Several graphene layers which stacked with each other are called Graphite and used in many Carbon Composites.…”

Contrary to its name, the "lead" in pencil is predominately made up of combination of graphite and clay or polymer, hence it can be considered as carbon composite. It has been proven that the more amount of carbon, the greater Young Modulus will increase and vice versa. Some researches on electric property of carbon composite also have shown that pencil drawn can be treated as a strain gauges and chemiresistors on paper. It means that in pencil's lead, the mechanical and electrical properties are related to one another. In this study, we applied a compressive load on pencil's lead and measured the effect on its resistivity. The results show that the resistivity will decrease while the strain will increase.

“…It was recently demonstrated that graphenic carbon (GC) is a suitable window material as it is deposited directly from a gas phase onto a silicon substrate and overcomes the inadequate adhesion by forming strong silicon carbon bonds . The inherently high bonding of the GC window material to a silicon frame not only hinders delamination but also acts as a gas tight barrier in contrast to graphene that adheres by van der Waals forces .…”

X-ray transmission windows for the low energy range, especially between 0.1 keV and 1 keV have been designed and fabricated based on graphenic carbon (GC) with an integrated silicon frame. A hexagonal and a bar grid support structure design have been evaluated. The bar grid design allows to substitute polymer-based windows with the advantages of higher transmission, better rejection of visible light and vacuum operability of the encapsulated silicon drift detectors (SDD). In addition, the high mechanical resilience of graphenic carbon is demonstrated by pressure cycle tests, yielding over 10 million cycles without damage. The data are complemented by bulge tests to determine a Young`s modulus for graphenic carbon of approximately 130 GPa. Additional finite-element simulation and Raman studies reveal that the mechanical stress is not homogeneously distributed, but reaches a maximum near the anchoring points of the free standing graphenic carbon membrane.
