Strongly coupled Coulombic system of a classical one-component plasma has been studied by using a two-dimensional (2-D) charged metallic particle system confined on a silicon (Si) wafer. The charge and the thermal motion of the particles are controlled by a high voltage on the wafer and an intensity of mechanical oscillation of the wafer produced by the sound from the speaker, separately.It has been demonstrated that the Coulomb coupling parameter for the particles GAMMA can be varied up to 2000. When GAMMA-240 (rotational energy is included in the estimation of GAMMA), the transition from the liauid to the Wigner triangle crystal phases is observed. The electrostatic plasma mode has been studied by measuring the spacial profile. and the frequency spectrum in the liquid phase (GAMMA-60) and compaired with the particle simulation results.

通过使用限制在硅 (Si) 晶片上的二维 (2-D) 带电金属粒子系统，研究了经典单组分等离子体的强耦合库仑系统。粒子的电荷和热运动分别由晶片上的高电压和扬声器声音产生的晶片机械振动强度控制。已经证明，粒子 GAMMA 的库仑耦合参数可以变化到 2000。当 GAMMA-240（旋转能量包含在 GAMMA 的估计中）时，从液态到液态的转变 观察到维格纳三角晶相。通过测量空间轮廓来研究静电等离子体模式。和液相频谱（GAMMA-60）并与颗粒模拟结果进行比较。
