二维电子气体系统的图案成微米霍尔棒可以用作霍尔磁传感器。以这种方式，弹道霍尔探测器已经被研究并成功使用。在这里，霍尔传感器的响应函数是在扩散状态下确定的，这使得该装置可以用作磁传感器来确定非均匀磁场分布。此外，霍尔杆的几何形状对该响应函数的影响，如圆角和探头的不对称性，也进行了研究，似乎是不可忽略的。
Two-dimensional electron gas systems patterned into micrometer Hall bars can be used as Hall magnetosensors. In this way, ballistic Hall probes have already been studied and used successfully. Here, the response function of a Hall sensor is determined in the diffusive regime, which allows this device to be used as a magnetosensor for the determination of inhomogeneous magnetic field distributions. Furthermore, the influence of the geometry of the Hall bar on this response function, such as circular corners and asymmetry in the probes, is also investigated and appears to be non-negligible.
