Our system made of two<br /><br />triangular potential barrier regions separated by a well region characterized by an energy gap<br /><br />Gp . Solving our Dirac-like equation and matching the solutions at the boundaries we express our<br /><br />transmission and reflection coefficients in terms of transfer matrix. We show in particular that the<br /><br />transmission exhibits oscillation resonances that are manifestation of the Klein tunneling effect. https://jhap.du.ac.ir/article_214_a4d59cbe4fc86b7e1d0b433e3db5c5b0.pdf
