In this study, morphological properties and Schottky diode application of mpg-C3N4 material were investigated. XRD, SEM and TEM analyzes of this material were performed. When the SEM image is examined, it is seen that mpg-C3N4 particles are coated on the surface homogeneously. The p-Si crystal was used as the base material and mesoporous graphitic carbon nitride material mpg-C3N4 was coated on the crystal with spin coating. Thus, reference and mpg-C3N4/p-Si heterojunctions were fabricated. Using the current-voltage (I–V) measurements of the diode, the ideality factory (n) and barrier height (Φb) values were calculated at the room temperature. These values of Ni/mpg-C3N4/p-Si/Al heterojunction diode were determined as n = 1.25 and Φb = 0.83 eV by the Thermionic Emission (TE) method. Furthermore diode parameters (n, Φb and series resistance (Rs) were determined with Cheung and Norde functions. Also capacity-voltage (C–V) measurements of this device were taken for different frequency values. Using this measurements carrier concentration (Na), barrier heights (Φb), Fermi energy level (Ef) and diffusion potential (Vd) values were determined.

介孔石墨氮化碳(mpg-C3N4)异质结二极管的应用

在这项研究中,研究了mpg-C 3 N 4材料的形态特性和肖特基二极管的应用。对该材料进行了 XRD、SEM 和 TEM 分析。当检查SEM图像时,可以看出mpg-C 3 N 4颗粒均匀地涂覆在表面上。以p- Si晶体为基材,在晶体上旋涂了介孔石墨碳氮化物材料mpg-C 3 N 4。因此,制造了参考异质结和mpg-C 3 N 4 / p -Si异质结。使用电流-电压 ( I–V) 二极管的测量值、理想工厂 ( n ) 和势垒高度 ( Φ b ) 值是在室温下计算的。Ni/mpg-C 3 N 4 / p -Si/Al 异质结二极管的这些值 通过热电子发射 (TE) 方法确定为n  = 1.25 和Φ b = 0.83 eV。此外,二极管参数 ( n, Φ b和串联电阻 ( R s ) 由 Cheung 和 Norde 函数确定。此外,该器件的容量-电压 ( C-V ) 测量值针对不同的频率值进行了测量。使用该测量值,载流子浓度(确定了 N a )、势垒高度 ( Φ b )、费米能级 ( E f ) 和扩散势 ( V d ) 值。
