One of the most challenging tasks for LED applications is emitting 100% polarized light from the device. Typically, this is achieved by introducing an additional layer of polarization filter which leads to losing half of the light intensity. To overcome this issue, one has to find a system with a high degree of photoluminescence (PL) polarization. A promising approach here is using magnetic...
Antiferromagnets (AFMs) are promising materials for spintronic and opto-electronic applications due to natural spin dynamics in the THz range and, at the same time, they have no net magnetization. This leads to the absence of stray fields which is a useful property for data storage applications. A promising approach here is to combine the unique magnetic properties of AFMs with the strong...
Lead-halide perovskite nanocrystals have emerged as high-performance semiconductors for efficient optoelectronic devices, especially in light-emitting diodes (LEDs) for bright and flexible displays. Atomic doping with transition metals other than lead has been shown to dramatically boost the luminescence of these nanocrystals. Yet, we still do not fully understand why these materials work so...
Two-dimensional infrared (2DIR) spectroscopy has been widely used in structure study and energy transfer of bulk samples. However, in the last decade, 2DIR spectroscopy has been extended to study molecules at interfaces. Our target was to develop a user-friendly 2D ATR IR spectrometer, which will benefit a broad group of laboratories and researchers, expanding the borders of regular 2DIR...
