The isolation of graphene has resulted in an increase in the interest in two-dimensional materials. These materials can be selected based on their electronic structure, ranging from semiconductor to insulator. Moreover, the vertical stacking of these materials into heterostructures results in new pr...

Silicon radiation detectors with minimum dead area in the sensor periphery are desirable and sometimes necessary for many applications in nuclear medicine, high energy physics, and X–ray science. The dead area typically includes a guard ring structure that is required for facilitating a uniform elec...

In preparation for operation at the High Luminosity LHC, the tracking system of the ATLAS experiment is replaced with a new inner tracker, the ITk. The innermost layers of this system must be designed to withstand a fluence of more than 10^16 cm-2 1 MeV neutron equivalents. At SINTEF, Norway, silico...

The increase in levels of air-pollutants due to growing urbanization and industrialization worldwide poses a major risk for human health as well as having bad effects on the global environment such as acid rains, photochemical smog, ozone layer deterioration and global warming. Exposure to hazardous...

Graphene and graphene-like 2D layered materials such as transition metal dichalcogenides (MoS2, WS2, etc.) have attracted tremendous scientific and technological research interest over the last one and half decade. These materials offer excellent possibilities for developing ultra-sensitive sensors ...

The upcoming High Luminosity LHC (HL-LHC) puts stringent requirements on the tracking detectors situated closest to the interaction point in the planned Inner Tracker (ITk) of the ATLAS experiment. 3D pixel detectors have been proposed as a candidate for the innermost layers of the ITk since these d...

Detectors with high radiation tolerance and high time resolution are required for charged particle in high physics and space applications. 3D detectors were introduced by S. Parker 1 in the middle 90’ and they represented a starting point for evolved device able to work at fluency up to 2 × 10^...

Minimisation of insensitive volume in silicon sensors is highly demanded in many applications for high energy physics, structural biology, synchrotron experiments and nuclear medicine. A large contribution to this insensitive volume is the guard rings and current terminating structures required in c...

Silicon radiation sensors typically have an inactive volume at the device periphery necessary to accommodate multiple guard-rings and current terminating structures necessary to deliver increased breakdown voltage and stability and to shield the active area from the defects induced by the dicing pro...
