论文摘要
平行磁场$ b $和潜在底物对偏见的ABC堆叠$ pn $和$ pnp $ trilayer石墨烯连接（ABC-TLG）的传输，电导率和FANO因子的影响。我们发现，在存在高磁场$ b = 1400 $ t的情况下，ABC-TLG还可以在两个新的发病率$ k_y $ values，除了通常的$ k_y = 0 $和能量价值的情况下，以两个新的发病率$ k_y $值展示新的klein隧道。实际上，通过$ PN $和$ PNP $连接的传输变成了单独的石墨烯（SLG）的三分离传输，klein隧道的出现在$ k_y = 0 $ = 0 $ and $ k_y = \pmκ$（$κ$）（$κ$）高度依赖于$ b $）。此外，电导率$σ$和FANO因子$ f $的行为与SLG相似，ABC-TLG的最低$σ= 3G_0/π$，最高$ f = 1/3 $ at $ b = 1400 $ t和$σ__{\ text {tlg}} =3σ_ {
The effect of a parallel magnetic field $B$ and a potential substrate on the transmission, conductivity, and Fano factor of a biased ABC-stacked $pn$ and $pnp$ trilayer graphene junction (ABC-TLG) is investigated theoretically at low energy. We discovered that, in the presence of a high magnetic field $B=1400$T, the ABC-TLG can exhibit new Klein tunneling at two new incidence $k_y$ values, in addition to the usual value of $k_y=0$ and whatever the energy value is. Indeed, the transmission of ABC-TLG via $ pn $ and $ pnp $ junctions is transformed into a three-separate transmission of single-like graphene (SLG), with Klein tunneling appearing at $k_y=0$ and $k_y=\pmκ$ ($κ$ is highly dependent on $B$). Furthermore, the conductivity $σ$ and Fano factor $F$ behave similarly to SLG, with ABC-TLG having the lowest $σ=3g_0/π$ and highest $F=1/3$ at $B=1400$T and $σ_{\text{TLG}}=3σ_{\text{SLG}}$.
