WebThe primitive translation vectors of the honeycomb lattice are vectors a1 and a2; the primitive cell is a parallelogram whose sides are these two vectors and the two dotted lines. WebWavelength-selective uncooled infrared (IR) sensors are highly promising for a wide range of applications, such as fire detection, gas analysis and biomedical analysis. We have recently developed wavelength-selective uncooled IR sensors using square lattice two-dimensional plasmonic absorbers (2-D PLAs). The PLAs consist of a periodic 2-D lattice …
WebIn Fig. 1, a graphene sheet with defined chiral vector and angle may be seen. The chiral vector can be described in terms of the lattice translational indices (n,m) and the unit vectors a 1 and a 2 (see Fig. 1), as shown in Eq. (1): In geometry and crystallography, a Bravais lattice, named after Auguste Bravais (1850), is an infinite array of discrete points generated by a set of discrete translation operations described in three dimensional space by where the ni are any integers, and ai are primitive translation vectors, or primitive vectors, which lie in different directions (not necessarily mutually per…
