Molecular beam epitaxy has led to quantum wells which confine electrons and holes in one direction and microcavities which confine photons in one direction. In this proposal, 2D and 3D confinement of electrons is studied by using a magnetic field of up to 14 Tesla to quantize the quantum-well energy levels in one or both of the directions perpendicular to the direction of growth of the semiconductor cavity. By applying no field, a field parallel to the layers, and a field perpendicular to the lasers it is proposed to compare carrier relaxation and microcavity lasing for quantum wells, quantum wires and quantum dots, respectively, using the same quantum well and microcavity. Although fundamentally conceived and oriented, this research is strategic for manufacturing of low- threshold microlasers for use in the information superhighway, optical data storage, large panel displays, etc.

分子束外延导致量子孔，这些井限制在一个方向上的电子和孔中，这些孔将光子限制在一个方向上。 在此提案中，通过使用最多14个特斯拉的磁场来量化垂直于半导体腔生长方向的一个或两个方向，研究了电子的2D和3D限制。 通过不应用磁场，与层平行的场，以及垂直于激光器的场，建议分别使用相同的量子孔和微腔，以分别使用量子孔，量子线和量子点比较载体松弛和微腔激光。 尽管从根本上进行了构思和定向，但这项研究是制造低阈值微型播放器的战略性的，用于信息超高速公路，光学数据存储，大面板显示器等。
